]]>If you do a lot of arts and crafts, need to glue something together at your home or office, having a reliable hot glue gun is a luxury. You want something that is safe, easy to use and durable.

There are also glue guns that you can adjust the temperature so you can glue many different types. Find out below what is the best hot glue guns for materials like foam, metal, glass, wood, ceramic, fabric and plastic.

Based on my test, the BSTPOWER is the best high temp hot glue gun for crafts or crafting. What I like about this glue gun is that it’s a hundred watts and I can change the temperature on it.

There’s a little indicator in the bottom and it has where you can do low temp at 100, 130, 160, 190 and 220. They also have increments in between. The highest temperature of this gun can get is at 220. Which makes the BSTPower

I also like that it has an indicator light. The light will turn off once the glue gun is ready. I sometimes forget that my glue gun is on and so that really stinks because I’m wasting electricity and of course wasting glue sticks

It has a really tiny fine nozzle. It works really well I don’t see it dripping out or anything like massive globs and it really has a comfortable fit in my hand. The glue gun does come with a chart which gives you a sense of which sticks need what temperature.

Overall, a really nice little glue gun. It is adjustable and you change the settings. The included little stand is really helpful so that you can set it out when you’re not using it. If you do a lot of arts and crafts in your house this really comes in handy.

The Surebonder PRO2-100 is ideal for small output industrial applications. The PRO2-100 produces 1 gram with a single pole and over 16 grams before needing to reheat to operating temperature. It is the best hot glue gun for fabrics.

It uses standard 7/16″ glue stick. It has an on/off switch and a rubber grip. The glue gun has a 100W PTC heater which allows for a quick recovery time. This gives the user maximum adhesive output and makes it perfect for any and all industrial applications.

You can also use the glue gun to bond wood, glass or ceramic. Surebonder also offers a large array of glue guns and glue sticks manufactured in the USA.

The CCbetter Mini Hot Glue Gun is a 20-watt glue gun and comes with 25 glue sticks. That is a wonderful amount to get you started on crafting projects. It really is quite compact and light. For me, this is the best mini hot glue gun in the market.

One feature I really like about it is that it is plug and play with on and off switch. Perfect if you want to bond something really quick. It is the best for kids too!

It also comes with a stand which is really helpful and allows you to use it in any angle. The cable length is 47 inches and I think that is a pretty good length.

This is another 20-watt mini glue gun that you can use for simple projects and DIY tasks. The Best Hot Glue Gun also comes with 25 glue sticks. It is also small and light. It does have an LED notification to let the user know that the glue gun is turned on.

This cheap hot glue gun comes with a variety of safety features like internal safety fuse and smart temperature control to prevent the glue gun from overheating.

I see a lot of people using it in the woodshop and home improvement industry too. You can easily do a carpet repair and other household DIY tasks with this glue gun. This glue gun is great for industrial use too.

When choosing a glue gun you need to decide if you need a high temp, low temp or dual temp model.

**High temp models –**can also be used for metal, wood, glass, porcelain and other harder to bond surfaces.**Low temp models**– for surfaces that are affected by heat like ribbon, foam, lace and fabric.

Glue guns have a wattage ranging from 10 watts up to 600 watts. The higher wattage models can heat your glue sticks faster. The most popular for home repair, carpet repair, school projects, crafts and office use are the 100-watt glue guns.

There are two sizes of glue guns:

**Mini glue gun –**perfect for children’s projects or if you want a to glue something really quick. Kids can use them easily.**Full-sized glue gun****–**for larger projects, for industrial use and for harder to bond materials. Usually, full sized glue guns have different temperature levels.

After a tiring day at the office, you just want to relax at the comfort of your home. Unfortunately, most of us have these tiny uninvited guests that can damage our beloved home and backyard, and we all know that they can bite really hard too!

So what can we do to kill these ants? There are some do-it-yourself methods but they are time-consuming and most of us don’t have time to do everything by ourselves. A pretty common and a very effective method is to purchase ant baits like the TERRO T300B Liquid Ant Baits. They are also readily available and easy to setup.

The Terro liquid ant baits are probably the most popular in the market today. Its active ingredient is borax, a highly toxic mineral for ants which makes it a exceptionally effective ant killer! While borax is dangerous for ants, it is very safe for humans. So you do not have to worry having it inside your house with your babies, children or even pets.

It is inexpensive and extremely effective against the most common household ants. The ant traps are in slim and thin plastic containers so you can easily slip them underneath the bed, in between appliances and on other parts of your house. Which also makes them out of the way so your children or pets can’t get into them.

You should place the bait where you see the ants and just leave it there. The bait will attract them and will kill them slowly. From my experience using this, 2-3 days and the ants are gone.

Just like the Terro ant bait, the Advion Ant Gel is a very effective bait for killing those pesky insects. Advion gel bait is easy to apply in residential and commercial properties. It is an odorless, clear gel inside a tube. You can use the included plunger to push the gel out of the tube, just a few drops and you can expect that the ants will swarm at it.

Before getting started, it is always wise to put on your safety gloves although the label does not require them. Keep note that Advion cannot be applied to surfaces that contact food or in place that is accessible to children and pets.

Once you get started, be sure to space each spot treatment a few inches apart. This lets more ants feed on the bait matrix at one time. For highly active foraging trails you can apply lines of the gel up to 3 inches long.

Most professionals exterminators that I know are using the Advion Ant Gel so you can expect that this is really effective.

The Talstar Pro is a little different than those two ant killers above. First, it is not just for ants, but you can also use this to kill roaches, termites, fleas, ticks, beetles, spiders and other pests. Also, while the Terro and Advion are ready to use baits, to use the Talstar you need to dilute it with water and put it in a hand pump sprayer or other similar pressurized sprayers.

It is easy to mix and the included label directions are easy to follow and apply. You can use this insecticide indoors and outdoors. The Talstar Pro is recommended if you’re encountering pretty bad infestations.

Another good thing about the Talstar is it is a long lasting product and you only need to apply it once every few months for general pest control. Additionally, it should not be applied more than once every seven days. Remember that!

As the name suggests, this ant bait is specifically designed to be used outdoors. A pack of Terro 1806 includes six large pre-filled ant baits that you can use right away and it is easy to setup. Just place it at the corner of your patio, garage, lawn or garden and it will instantly attract most household ants and kill them before they can get inside of your home.

It also inexpensive and working extremely well. As always, even though these baits are not extremely harmful to humans and pets you should keep them away from their reach.

The Suspend Sc Insecticide is a great alternative for the Talstar Pro. It is a concentrated liquid insecticide that can be applied indoors and outdoors. It can also kill most common household pests like ants, bugs, spiders and cockroaches.

You need to mix the insecticide with water in order to use it. It is a very effective product but you should avoid applying it on the flooring, furniture and frequently used areas of your house.

To get rid of the most common household ants like:

- Carpenter ants
- Sugar ants
- Fire ants
- Ghost ants
- Crazy ants
- Leaf-cutting ants
- Flying ants

The most simple and time efficient method is to use ant baits or ant traps to kill them.

Don’t worry too much about finding their nest. Chances are you’ll have a hard time because it is well hidden and it is almost impossible to follow the ants especially when they are behind the walls and hard to reach areas of your home.

If the infestation is tolerable, my suggestion is to purchase ready to use baits like the Terro T300B. Place them in your bathroom, kitchen, on wall cracks and on other parts of your house where you see ants. The bait will attract and kill them 100% of the time.

On the outside of your house, your garden, lawn, garage or yard, you can use ant baits like the Terro Outdoor.

By doing this, it will save you a lot of time than preparing or mixing your own solution. But if you have a severe infestation you can seek professional pest control services. If you want to do it on your own, consider using the same product that pest control companies are using like the Talstar Pro.

First, you have to inspect your car for leftovers and juices or drinks that left inside your vehicle. Clean the car, vacuum the interior then place the bait near the location of the ants. You can either use the Terro Ant Baits or the Advion Ant Gel.

I like to use the Terro ant baits more because the gel is placed inside of what they called “bait stations” and because of them, I have peace of mind knowing that they can’t damage my car interior. Although, I’m pretty sure that they are harmless, but hey, prevention is better than cure.

If the do-it-yourself solutions are too much of a hassle to you, then using ready made ant baits is the way to go. They are easier to setup and works extremely well. There are many ready-to-use ant baits available in the market. You just use them as it is and place them somewhere around your house. Soon, you’ll have an army of dead ants laying around.

]]>If you’re tired of sharpening your pencils manually and you want an easy and automatic way to keep your pencils sharp and ready for use at all times, you should consider getting an electric pencil sharpener. This little gadget is perfect for keeping any type of pencils sharp and ready for use, including colored pencils, makeup pencils and even cosmetic pencils.

These electric pencil sharpeners are best for teachers and students in classrooms, for artists, studios and can also be used in the office and in your home.

For that nice, long, clean and pointy tips on your pencils you might wanna try the School Smart Vertical Electric Pencil Sharpener. It is quick (will only took just a few seconds), clean, powerful and faster than most electric pencil sharpeners in the market today.

You can use it with almost all types of pencils including watercolor pencils and art pencils. It is more popular in classrooms and in art studios.

The blades are very pencil friendly you can expect that there are little to no pencil breakage while sharpening pencils.

The School Smart has a huge shavings receptacle that you can easily access to empty the electric sharpener.

The X-Acto SchoolPro is a heavy duty and also a powerful sharpener. It is fast and gives beautiful pointy tips. A great feature of the X-Acto School Pro is it can accommodate up to 6 different pencil sizes. It also has an auto stop feature that will prevent the sharpener to eat the entire pencil.

Another good thing about this sharpener is it is slightly quieter than other electric pencil sharpeners. It also has a large bin for the shavings. If you want an all around and heavy duty electric pencil sharpener this is your best bet.** **

Another great pencil sharpener on this list is the OfficeGoods Electric & Battery Operated Pencil Sharpener. This is a bit different than the two pencil sharpeners above. First, it has 3 different sharpening settings as shown in the image above. It usually takes 6-10 seconds to sharpen a new pencil. For refreshing a pencil it just usually takes 1-3 seconds.

Second, you can use the OfficeGoods sharpener without the cord and charging adapter. You can use batteries on this pencil sharpener for added portability. I will give OfficeGoods two thumbs up for this amazing feature. But please, do take note that **you can not charge this sharpener using your laptop** because as OfficeGoods stated, it may damage your laptop!

And lastly, this pencil sharpener has a built-in safety mechanism that can be found at the shavings cover. The sharpener will not run unless the sharpener is not fully closed. This feature is for added security for your kids.

Designed for high volume use in the classrooms and offices the LINKYO Electric Pencil Sharpener is a heavy duty and has a solid feel pencil sharpener. LINKYO claims that the optimal life time sharpening is up to 3000 times!

It can sharpen wooden pencils, standard graphite pencils and color pencils. Like the other sharpeners on this list, the LINKYO also has an auto stop feature that ensures perfectly sharpened tips. It has a really large shavings receptacle that rarely needs emptying according to LINKYO. But of course, if you want it cleaner, you will need to empty it every now and then. It also makes the device to look good.

A nice added feature of this sharpener is the auto jam release. If ever you pencil got stuck you just need to press the pencil down to release it easily.

The OfficePro is an inexpensive pencil sharpener and is a good alternative if you want portability by not using any cords. This device is powered by 4 AA batteries and they are shipped together with the pencil sharpener. It is light, compact and have enough power to sharpen pencils although it is not as powerful as the School Smart and X-Acto.

The OfficePro works great on normal graphite, lead and colored pencils. It also has an auto stop feature so you can expect nice and sharp pencils with minimal waste.

An electric pencil sharpener is an electronic device used for making sharpened writing points of a pencil easily. It is one the useful item in stationery items list which can be used in offices, homes or schools. Electric pencil sharpeners are available in the market in different sizes, shapes and prices. Mostly electric sharpeners are battery-operated.

Before the invention of electric pencil sharpeners, pencils was sharpened using a manual sharpener, knife or a blade. This method has some safety issues and also sharpening was not uniform. Electric pencil sharpener overcame all these limitations of this old fashioned pencil sharpening.

It made pencil sharpening faster, easier, and gave better uniform sharpening. Since electric sharpeners are made by engineers, it attained its position in stationery items of offices, homes and schools easily.

There are various types of battery operated pencil sharpeners today with different sizes, shapes, colors, usability and prices. You need to buy which will be most suitable for your need.

Here is some features of latest pencil sharpeners

- Pencil sharpeners which have more than one hole for sharpening pencils with different pencils sizes.
- Heavy duty pencil sharpeners are available for institutions which have frequent usage of sharpening. These types will have large storage room for storing sharpened materials. So that frequent removal of waste from pencil sharpening is not needed.
- Sharpener with silent motor.
- Can be used in sharpening different types of pencils.

The good thing about this type of pencil sharpener is that it’s really accurate when it comes to sharpening your pencils. You never have to worry about it over sharpening your pencils too because it has a built-in sensor that will cause it to stop the sharpening process immediately when it has detected that enough wood has been shaved off.

It will also help you prevent pencil waste so that your pencils can last longer. If you were to sharpen your pencils manually with a knife blade or a manual pencil sharpener, you will find that in most cases, you have to sharpen them several times before you can make them sharp and usable.

When it comes to buying the best electric pencil sharpener, you need to choose a model that not only looks good on your desk but also one that comes with a cutting blade that is constructed from heavy duty durable steel. This is especially important if you need to sharpen a lot of pencils.

Heavy duty models have more powerful motors so they can sharpen more pencils without getting overheated or burned out easily. Also, make sure that the model is capable of shutting the motor off automatically when sharpening is done and that it has a large and easy to clean shavings receptacle or tray.

Nevertheless, it is important to note that most models will get hot in the motor housing area when they are overheated. When this happens, it will shut off automatically and you will need to let it cool down enough first before you can resume your sharpening.

The difference between a heavy duty model and a normal one is that the former has high-powered steel alloy blades that can sharpen your pencils in seconds and it can also operate for a much longer period time, thus making it possible for you to sharpen a lot of pencils before it gets overheated.

Besides choosing a model that has a heavy duty motor for stall-free operation, you should also make sure that it features thermal overload protection because this feature is seriously going to help you increase the motor life. If you find the sharpening noise to be annoying, you might want to get the quietest pencil sharpener you can find.

This can be very helpful if you need a quiet pencil sharpener for an environment such as a classroom or office where any unnecessary noise can cause disturbance and interrupt the attention or concentration of others.

If you plan to use it to sharpen your cosmetic pencils so that you can get factory fresh point each and every time, you need to choose a model that is designed for sharpening make up pencils.

This is because you need a different blade mechanism that is just strong enough to cut through the tough outer shell and at the same time fast enough to cut through the soft make-up portion of your cosmetic pencil.

To put it briefly, an electric pencil sharpener is a lot more convenient and way better than sharpening your pencils manually because it will not only save you time but also help you make your pencils last longer by preventing any unnecessary pencil wastes. Be sure to choose a model that is suitable for your sharpening needs and get a heavy duty model if your budget allows it because it will be more sturdy and capable of sharpening more efficiently.

Hello folks! Here are some Geometry terms to help you understand geometry better. It is easy to memorize and you can print this and use as a quick guide.

The longest side of a right-angled triangle. The hypotenuse is also the side opposite the right angle.

With no limit or end, when something continues endlessly.

A whole number (-3,-2,-2,0,1,2,3). A number with no fractions or decimals.

A side of a triangle. In a right triangle, the sides adjacent to the right angle.

A line is straight, has no width and continues forever in both directions.As lines have no end points they are usually named using any two points that fall on the line in any order:

The double headed arrow on top of the letters shows that the points A and B represent a line which continues infinitely in both directions.

A Line Segment is like a line but has two endpoints. A line segment is named using the two endpoints. Because the line does not continue endlessly in either direction the line above has no arrow heads.

A Ray is like a line except that it continues infinitely in only one direction and starts from a point. A Ray is named similarly to a line, using two points on the ray. However, the first point must be the end point. The arrow also only has one head signifying that the ray continues forever in one direction.

To multiply a number by itself. E.g 5² = 5 x 5 = 25.

The square root of a number is the value that when multiplied by itself gives the original number. E.g. √25 = 5 because 5 x 5 = 25.

A Vertex is the end point or corner where two rays/line segments meet.

]]>You can find the area of a triangle with a straightforward formula: **½bh (½ x base x height).**

But first, what are the base and height? The base(b) can be any side of a triangle, however, the height you use in the formula must start (at a right angle) from this base. The height(h) is the distance perpendicular(at a right angle) from the base to the highest point of the triangle.

Tip: Get a calculator that is fast and accurate for your geometry subject. Read the article here.

So we have the following formula: **Area of a Triangle = 1/2 x base x height**

Now let’s give it a go with a worked example… Whats the area of the following triangle? Using the formula: Area = ½ x b x hbase = 10height = 4

So, area = ½ x 10 x 4 = 20 units² Area of a Right Triangle

Because of the shape of a right triangle, you can use the length of two of the sides (the legs) as the base and height. You must use one leg as the base and the other as the height – it doesn’t matter which way round: The third, longest, side is called the hypotenuse. If you have the length of one leg and the hypotenuse it is pretty straight forward to use the

If you have the length of one leg and the hypotenuse it is pretty straight forward to use the Pythagorean theorem to find the length of the other leg. Let’s try that out… Right, this is a right triangle which means we can use the leg lengths as the base and height.

But, we’re missing a leg length, instead we have the length of the hypotenuse (13). So, let’s use the Pythagorean theorem to find the length of that other leg: ** Pythagorean Theorem: a² + b² = c²** – where a and b are the legs and c is the hypotenuse.

Let’s put the values that we have into this formula and solve it:

- a² + 5² = 13² a² + 25 = 169
- square the 5 and 13a² = 169 – 25
- rearrange to solve for aa² = 144
- subtract 25 from 169a = √144
- and finally square root 144 to find a a = 12

Now we have the two legs we need: a= 12, b = 5

We can use these values for the base and height of the triangle: Area 1/2 x 12 x 5 = 30 units²

Why is the area ½bh?

The area of a rectangle is base x height, the area of a triangle is half of the base x height. So, a triangle is half the area of a rectangle with the same base and height. If you look at the diagrams below you can see that the black rectangle has twice the area of the triangles with the same base and height: Area of an Equilateral Triangle

In an equilateral triangle all the sides are the same length. This means you can use a special formula to calculate the area using the length of the sides (If you have the height of an equilateral triangle you can still use the original formula).

]]>Here you can learn how to find the area, circumference, arc length, sector area, radius, and diameter of a circle. The formulas are easy to follow and you’ll find them all below. As always you can use a geometry graphing calculator for this. A circle is a set of all points in a plane(flat surface) that are the same distance from its center.

In other words, it’s a shape made up of a curve that is, at all points, the same distance from a single point(the center). When you’re working with circles, you’ll need to know about Pi – I’ve covered that too. You can find the area of a circle using a simple formula: ** Area = πr²**.

However, before you can use this formula, you’ll need the radius (or diameter). I’ll walk you through how to find the area with a couple of examples. Want to know how to quickly find the circumference? All you need is the following simple formula: *Circumference = πd*

But, same as the area, first you need the diameter or radius. The radius and diameter are two important elements of every circle. The diameter is the distance from one edge to the other, passing through the center point. The radius is the distance from the center point to the edge.

I’m going to show you how to find the length of the radius or diameter. An arc is a section of the circumference, we would call this one AB, after it’s end points. You can find the length of an arc with the radius of the circle and the arc’s central angle.

A sector is a section or part of a circle, shaped like a slice of pie. You can find the area of a sector with the radius and the arc’s central angle. People have been intrigued by this number for thousands of years now – but what makes it so special? And why do we use it in circle formulas? Pi gives us the relationship between a circle’s diameter and its circumference.

]]>Want to know how to quickly find the length all the way around a circle? All you need is the following simple formula: *Circumference = Pi x Diameter *Also written as πd. Or, you can use the following formula: *2πr *

Because the diameter is equal to 2 x radius(2r). Now you have two simple formulas to calculate the circumference of a circle. You can use a scientific or a graphing calculator that is suitable for geometry. Read some calculators here.

The radius is the distance from the center point to the edge.The diameter is the distance from one edge to the other, passing through the center point of the circle. Pi is a special number in geometry, it’s equal to approx. 3.14159.. and is represented by the symbol π.

Try the worked examples below to see how to use the radius, diameter and pi in the formula:Now try the short worked examples below…1) What is the circumference of the below circle? Here you have the radius of the circle; 7Circumference = 2πr

Answer: 2 x 3.14(π) x 7 = 43.962)

What is the diameter of the below circle? This time we have the circumference; 30

It’s easy to work backwards and find the diameter from the formula:30 = πd

All you need to do is rearrange the formula to find d:d = 30/πDiameter = 9.55

Today’s short lesson is about Triangles. Make sure you are using a graphing calculator. For more info check these graphing calculators.

Triangles are important geometric shapes. In short, they are polygons with three sides, three interior angles, and three vertices(corners). When labelling a triangle, you use uppercase letters for the vertices (and their

corresponding angles).

The opposite sides are then labelled with the same letter in lower case. The letters used to label the vertices are also used to name the triangle – this means you would name this one as triangle ABC. The interior angles always add up to 180°. Knowing this, can you work out what the size of the missing angle above is(at vertex A)?

There are six different types of triangles. Three are classified by the size of their angles: Right, Acute & Obtuse. The other three by the length of their sides: Equilateral, Isosceles & Scalene. Special right triangles have side length ratios which you can use to find missing side lengths.

We’re going to look at two different types: The 30-60-90 and 45-45-90 (isosceles right). A right triangle has one right angle. A right angle is 90° – a quarter of a full turn. You can easily calculate the area from the length of the two legs.

The three sides of a right triangle are called the legs(the two shorter sides) and the hypotenuse(the longest side). The

Pythagorean theorem states that if you square the lengths of the legs and add them together the result will be the square of the hypotenuse.

A Pythagorean triple is a set of three integers that fit the formula a² + b² = c².

They are written in the form (a,b,c). These three numbers are the side lengths of a right triangle. Pythagorean Triples are commonly used in Pythagorean theorem problem and are very useful to know.

]]>**Today’s math tip is about Circles: Area of A Sector.** A sector is a section or part of a circle – shaped like a pie slice. It is enclosed by the radiuses (radii) of the circle and an arc (where the sector meets the circumference). The area of a sector can be easily found with a formula which uses the radius of the circle and the sector’s central angle: The central angle is located at the sector’s vertex, this is the point where the sector meets the center point of the circle. Be sure to use a best graphing calculator so you have an easier time to input this formulas.

The radius (r) is the distance from the center point to the edge of the circle. The first part of the formula is πr² – this is the total area of the circle. In the next part of the formula we multiply the total area of the circle by central angle/360° – this is the fraction of the circle that the sector covers.

So, in short, to get the area of a sector, you multiply the total area of the circle by the fraction that the sector covers. See how in the worked examples below. If you already know the fraction of the circle that the sector covers, you can simply multiply the area of the circle by this.

For example, if we have a sector that covers exactly a quarter of the circle (a 90° angle), then you can multiply the area of the circle by ¼ (πr² x ¼) to get the sector area.

What are the areas of the following sectors in the diagram?i) ADB ii) BDCiii) ADCAnswersi)Radius = 7 cm Central angle = 72°Substituting the radius and central angle into the sector area formula:ADB = (π x 7²) x (72/360)= 153.94 cm²(area of the circle) x 0.2(1/5 of the circle)ADB = 30.79 cm²ii)Radius = 7cmCentral angle = 90°

We already know the area of the circle (π x 7²) from the previous question. Circle area = 153.94 cm²90° is exactly 1/4 of 360° this tells us that the sector covers exactly 1/4 of the circle:BDC = 153.94cm² x 0.25(1/4) = 38.485 cm²iii)Radius = 7cm Central angle = 72° + 90° = 162°153.94 x 162/360ADC = 153.94 x 0.45 = 69.27 cm²

When there are two sectors in a circle the smaller of the two is called the minor sector, it has a central angle less than 180° and covers less than half the area of the circle.

The major sector is the larger sector and has a central angle greater than 180°, it covers more than half of the area of the circle.

A semicircle is a sector which covers exactly half of a circle and has a central angle of 180°. It is enclosed by a semicircle arc and the diameter of the circle.

An octant is a sector which covers 1/8 of a circle and has a central angle of 45°.- A sectant is a sector which covers 1/6 of a circle and has a central angle of 60°. A quadrant is a sector which covers 1/4 of a circle and has a central angle of 90°.
