This is a cool science experiment to show what a great heat conductor water is. You'll need some balloons, a candle and some water. Check it out and be amazed! Common sense tells you that it's impossible to boil water in a paper bag, but this classic parlor trick was a favorite of the Victorian magician. The real difficultly in performing this effect is making it look harder than it is! As you might imagine, the secret lies in yet another amazing property of water - it's ability to conduct he...
In this video tutorial, viewers learn how to make an erupting volcano with soap. Begin by adding some vinegar into a flask/baker. Then add some soap into the vinegar and stir it by shaking the flask/baker. Users may choose to add some food coloring to make the mix look more like lava. In a separate, add some water and baking soda. Then stir it to mix. Pour the baking soda solution into the soap and vinegar mixture. This video will benefit those viewers who are interested in science and experi...
In this fascinating "how to" video, you will see how a simple process creates the illusion of ice that is burning. Only a few items are needed to enact this scientific experiment. As the narrator describes, "Calcium carbide reacts with water to form acetylene gas." To illustrate, the video shows a bowl of ice cubes, to which the special ingredient is added. As the ice melts into water, it reacts with the calcium carbide, forming the high flammable acetylene gas, which is often used in welding...
Ever wonder how to make your very own faux night vision goggles? Well, Mr. G shows you exactly how to make your own night vision "glasses". Step by step, soley using household products. This experiment is just too good to be true. A foolishly easy experiment that will make you laugh and cry at the same time. This video is just for fun, don't let it fool you!
This video shows how sublimation works. The instructor shows how to mix bubbled water, ice water and dry ice to create dry ice smoke. He is essentially making a hand made fog machine. This task must be done carefully because if the solution is isolated and concealed it will build pressure and possibly explode. Take extreme caution in doing this home experiment. The instructor also shows you how to make music spoons using temperature changes on the metal.

Try out this science experiment... demonstrate pressure and volume. Watch this video tutorial to learn how to create an explosion with liquid nitrogen and a plastic bottle. See the demonstration of the exploding reaction of the pressure build up in the bottle.
This experiment is very easy and inexpensive. It can be done at home. You will need a bowl, some water, some pepper, and some soap. You can use your finger to repel pepper, to the sides of the bowl. Simple, but fun.
Have you ever wondered what your DNA looks like? You have probably heard that DNA is a double helix, which is a pair of parallel helices intertwined about a common axis, but how do we know that? How can people look at DNA?
Check out this simple experiment using running water from a tap, and air blown through a straw, as it flows over the back of a vertically hanging plastic teaspoon are used to demonstrate the Coanda effect. Here the attachment of the back of the teaspoon to the flowing stream of fluid (air or water in this case) is what is referred to as the Coanda effect. Watch this how to video and you will be able to create the Coanda effect with your kids at home.
Vinegar and baking soda (and red food coloring if you're going all out) combine to make quite the little explosion.

In this video, we learn how to do an animal blubber (fat) glove experiment. You will need: a big bowl with ice water in it, 4 plastic bags, thermometers, and some vegetable shortening. To start, you will take the shortening and scoop it into plastic bag and then stick one of your hands in it. After this, stick two bags over your opposite hand with the temperature into it. Then, you will stick each of your hands in the ice water and see which one lasts longer in the ice water. The fat should k...
In this tutorial, we learn how to experiment with dry ice. You can buy dry ice from any grocery store, so grab that and you will also need some soap. After this, grab the dry ice with some thick gloves and set aside. Then, put some hot water inside of a container with some soap. Put the dry ice last inside of the container. After you're finished, you can wait to see the reaction occur! It will start to smoke and make different noises which is fun to watch and see! When done, clean up your are...
It is a well known fact that due to the rotation of the Earth about its own axis has a bulging effect on the equator and a slight flattening effect at the poles. This experiment tries the reproduce the same effect using simple materials.
From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts.

Newtons proposed the concept of inertia. According to him an object at rest tends to stay at test and an object in motion tends to continue in motions unless acted up on by an external force. This is the principle of inertia. The tendency of the body to continue to stay as it was is called its inertia. You can demonstrate this principle with a simple experiment. As shown in the video when the hoop is pulled out the pen cap falls in to the bottle. Here the hoop is acted upon but the cap is not...

If you've ever taken high school chemistry, you may already be familiar with the ability of liquid nitrogen to freeze soft object so hard that they will shatter. This video will teach you a fun experiment utilizing this property of liquid nitrogen. It invovles gummi bears frozen and soaked in water or liquid nitrogen (or not, for the control) and then smashed in a most satisfying way.
Gummi Bears are great for science experiments due to their gelatinous makeup. In this video you will learn how NOT to make a Gummi Bear conduct electricity, but in fact how to use them to demonstrate osmosis and crystallization by preparing them for conductivity.
An electrophorus is a type of capacitor that generates electrostatic energy. Most of you probably know this force as static electricity, the domain of door handles and polyester shirts. It can be used for all sorts of other fun science experiments though, and this video will show you how an old hard drive, some plastic, Styrofoam, foil, a cat, and other simple materials can be used to make a a simple functioning electrophorus.
