Try out this science experiment... a classy chemical demonstration. Watch this video tutorial to learn how to make a foamy elephant toothpaste chemical reaction. There's a reason why they call this elephants toothpaste.

Look, what candle can be made of a peanut and a potato. Make a flaming candle with a peanut and a potato. This is a neat survivalists' trick.

Make your own lava lamp using common household materials. You will need:

A demonstration of limonene extraction from orange peels used in Organic Chemistry labs. This demonstration is conducted by Dr. Scott Allen, Assistant Professor, Chemistry/Physics, University of Tampa.

A demonstration of the technique of extraction used in Organic Chemistry labs. Separate solubles like two liquids or two solids using this technique of extraction. These demonstrations are conducted by Dr. Scott Allen, Assistant Professor, Chemistry/Physics, University of Tampa.

Make your balloon "un-popable"!!! The trick is to fill the balloon with water so that it will absorb the heat and keep the rubber balloon surface cool. The flame will pop any balloon that is just filled with air. Cool science experiment trick to show off.

Watch what happens when Coke is mixed with wax. Learn how to do this cool science experiment yourself. Can anyone explain the science behind this??? You will need Coke (diet or regular), a glass test tube, and a candle. Break off a chunk of wax from the candle, put it in the test tube, heat the test tube until the wax is boiling and then quickly add to the coke.

Explore the universe in your microwave. Measure the speed of light with chocolate. The wavelength of light creates hot spots in the microwave that you can measure to show the speed of light. Chocolate has never been so useful.

It Really Sounds Like a Chicken! Have fun with your friends and family when you build this little device that sounds just like a chicken. This is also a great example of how sounding boards work. The cup makes the vibrations louder while the wet paper towel provides friction to create the sound.

Make Your Own Erupting Volcano!

Learn how to make this spooky, amazing floating static orb.

Watch this video tutorial to see how to make extremely simple scales. This scale is useful when you want to weigh small portions of a substance (like a few grams of powder). It is difficult to get real weight using these scales though. To make this homemade scale, you'll need a plastic bottle cap, a plastic bottle or box, a 9v battery, clear sticky tape, glue for the plastic (epoxy or fast-hardeneing), scissors and a screwdriver.

Forget about the weather channel. Radio and TV seem not able to predict the darn weather anyway. Make Your own barometer within the next few minutes! Become the weatherman of the house! You will need an empty jar, scotch tape, a balloon, a tubber band, scissors, a straw, a ruler, a sheet of paper and a marker.

You will need round shaped balloons. Blow up your balloon the size of a fist. If you make it too big, it is hard to work with. Next, take a balloon and cut off the neck. Stretch the balloon over the inflated one. Repeat these steps until you have a bouncy balloon ball.

Learn how to make a copper sulfate crystal. Warning: Copper sulfate is not good for your skin, so if you get any on it, clean well with water. If you eat it, call a doctor. You will need once cleaned out egg with a hole in the top, some copper sulfid (you can get it in garden shops), and 60 ml of hot water. Easy way to make your own crystals.

Holography is the scattering of light from an object, which is recorded and reconstructed to create the hologram. As the viewer or viewing mechanism moves, the image appears three dimensional. This instructional video shows how to craft 3 dimensional holograms using scratched arcs on a reflective surface. Using a compass, a picture, and Plexiglas, you can create glowing images that shift and turn inside of a 2 dimensional plane. Who would of thought? Now you can make your very own holograms at...

This will blow you away! 2 unopened 12 ounce cans of cola weigh the same, right? No they do not. That's why Diet Coke floats, but regular sugared Coke sinks. The extra weight comes from the natural sugar in Coca Cola and Pepsi that is not present in a can of diet.

A spectrometer is an optical instrument used to measure properties of light over a specific portion of the electromagnetic spectrum. This video will show you how to make a spectrometer out of a cereal box and a compact disc. This spectroscope is sure to amaze your kids for a nifty science project.

You need soap, cloth strips and a big bowl. Oh and of course dry ice. This takes a couple of minutes to explode so be patient.

Ian uses round magnets, pencil, clay and glass slide to work his magic science experiment. Magentic levitation is said to be a solution for energy costs of trains because it cuts down friction and creates what is mythically regarded as a perpetual energy motor. This is an interesting toy model of how the maglev trains and large scale generators work
