The original lava lamp actually isn't something you would want to make or break open since you would have to contend with electrical wiring and toxic chemicals. Fortunately, you can make a facsimile of a lava lamp without the risk of electrocution or poisoning. See how to make a non-toxic rechargeable lava lamp.

This is a classic chemistry demonstration in which salt crystals are grown on a cardboard tube. See time lapse photography of the crystal growth.

If you drop Mentos candies into diet cola you get a shooting fountain of liquid. You can use another liquid to get a fountain of liquid that glows in the dark!

Add drops of food coloring to milk. If you touch the milk, your finger gets wet but nothing really happens. If you add the secret ingredient, the milk will swirl the colors around, as if by magic.

This video shows how you can cause pepper sprinkled on ordinary water to skitter away from your finger. The project is a nice way to illustrate the concepts of emulsifiers and detergents.

This video shows how to use dry ice and bubble solution to make a stable 'crystal ball' filled with swirling fog.

Ordinary Halloween jack-o-lanterns are pretty awesome, but a jack-o-lantern filled with green fire is even better. This is a simple effect to achieve, relying on basic chemistry.

Alum crystals are some of the easiest and quickest crystals you can grow. This is a time lapse video that shows you what to expect when growing alum crystals.

See Magic Rocks grow through the magic of time-lapse photography. Modern Magic Rocks grow more quickly than the old Magic Rocks, plus the colors seem more vibrant. This video compresses 12 hours of crystal growth into a minute and a half.

See how to perform a blue color change chemistry demonstration using household chemicals. The reaction goes from pale blue to opaque sky blue to translucent royal blue.

This video examines how mood rings work as well as what common mood ring colors are and what mood ring colors mean.

Learn how to use a common copper-based household product to produce vivid green flames. This video shows you what to do and what to expect.

This video explains how to make a crystal ball of ice that glows lit from within by LEDs. The ice bulb can be used in drinks, fountains or anywhere you like. The ice bulb can be made in any single color or you can make a multicolored sphere.

This is a video of a science "trick" where you place a glass over a flame that is sitting in a dish of water. When the flame is extinguished, the level of the water in the glass rises as if by magic.

Light a bill on fire, yet it won't burn! Actually, it will burn unless you know how to do the trick. This video explains the science behind the burning money trick and shows you what to expect.

Here's a look at some of the materials that glow when exposed to a black light, including living organisms and common everyday chemicals.

This video shows you how to make fireballs that burn with a flame cool enough that you can juggle them or use them for other types of fire displays.

See how to make your fingers smoke, without any fire. Also, if you perform this project in the dark, your fingers will glow an eerie faint green. This video shows you how to perform the smoking fingers trick.

You can gain information about the chemistry of a compound by the color of flame it produces. This video explains how to use common potassium compounds to produce violet flames.

This video shows how to make an easy window paint that will coat the glass with crystals that resemble frost. Footage includes time-lapse photography of crystal frost growing on a window.

This video tutorial demonstrates how to grow your own alum crystals, plus time lapse photography shows you what to expect from the first few hours of crystal growth.
