How To: Light a bulb in a microwave or near powerlines
In this video watch a simple experiment of lighting a bulb and a fluorescent tube. Makes you wonder if being so close to power lines radiates people. Hmmmmmmm
How To: Rip a Penny in Half
No, we're not lying. But before you try and tear a plain old penny in half, you should probably watch this video first or you may hurt your fingers. While ordinary pennies are very, very difficult to rip, if you get rid of the zinc core you are left with only the thin copper shell, which is itself very easy to tear apart.

A science experiment for all ages. Keep the kids busy over the holiday. This demonstration will entertain them for hours. You can have fun making one for each of the kids in your family. All you need is a penny and a bottle.
How To: Levitate bubbles using dry ice
Another of my Halloween demonstrations. This simple but amazing video explains how everyday bubbles can float on a magic layer of air. It all has to do with density of air and some dry ice.
How To: Make a really foamy reaction with elephant toothpaste
Elephant toothpaste is the name given to the catalyzed decomposition reaction of 30% hydrogen peroxide that uses soap to collect the oxgen gas that is produced. It is a favorite of most students at chemistry shows.
How To: Make water rapidly crystallize

How To: Make an indoor flame thrower
When you use lycopodium powder, it explodes into flames when it is exposed to fire then dust form in this experiment. Be careful don't accidentally set your house on fire.
How To: Use the flame test to determine an unknown metal
The flame test is used to visually determine the identity of an unknown metal of an ionic salt based on the characteristic color the salt turns the flame of a bunsen burner.
How To: Dissolving polymer experiment
Styrofoam is a polymer and when brought into contact with acetone the polymer breaks down into its monomers. This demonstration shows the process of depolymerization. It looks pretty cool.
How To: Make an aluminum iodine volcano
The reaction of aluminum metal and iodine creates a plume of purple iodine while creating glowing aluminum iodide. A very interesting reaction.
How To: Make a magnesium reaction in dry ice
This reaction is between metallic magnesium and carbon dioxide. Magnesium reacts with oxygen in the air to form magnesium oxide, but when the only source of oxygen is from CO2 the reaction becomes much more energetic. The products are white magnesium oxide and black carbon.
How To: Instantly freeze soda experiment
The trick in this how-to video works with any carbonated beverage (never use beer). Take your beverage and cool it down to a temperature around 20F or -7C. Either the freezer or outside if it is cold enough. When opened it will freeze instantly.
How To: Make an indoor hydrogen rocket
The picture may look like a mushroom cloud, but it is actually a can filled with hydrogen exploding. The can is fired into the ceiling. This demonstration still needs a little improvement in the area of safety (but it looks really cool). The problem is the partial pressure of hydrogen drops as the gas escapes and is replaced with air. This causes the reaction to be an explosion instead of a flame. Hydrogen is a tempermental element like that.
