Introduction: How to Make a Lava Lamp - Easy

The World's Easiest Lava Lamp.
This is an easy, fun science activity that is great for any age. In fact, our video crew eneded up taking the extra bottles home to show their friends. It is also a great demonstration of liquid density, the release of gases in a chemical reaction, acids and bases, intermolecular polarity, and well, just plain science coolness. Watch the video, read the instructions (link below) then TRY IT!

You can try making an air pump underneath but I recon the construction won't be small and beautiful.
