Here’s how to make an Alka-Seltzer version of a lava lamp from stuff around the house – “Have you ever caught yourself hypnotized by a lava lamp? You hold it in your hand, move it slightly while inside the liquid quivers and separates into different shapes, and colors. Then you look at the price tag, and put it back. Fortunately, you can make a simple home-spun version. It won’t look exactly like one of those store bought ones, but it will be a fun project and you will learn a thing or two about chemistry while you’re at it!” [via] – Link.
