This is what happens when a coke can meets some flowing lava.

This is a classic chemical reaction. It's called the iodine clock reaction. There are several variations of how this chemical reaction can be performed using different chemicals than the ones I used in the video. You can order clock reaction kits from several science related websites. You can also use simple store bought chemicals like vitamin C, iodine, hydrogen peroxide and starch. A quick internet search will turn up multiple ways of performing the experiment.

So this experiment is the Chladni plate experiment. I used a tone generator, a wave driver (speaker) and a metal plate attached to the speaker. First add sand to the plate then begin playing a tone.

As the frequency increases in pitch the patterns become more complex.
