We present the results of using autocatalytic chemical reactions to drive wave dynamics. Using the chlorite and thiourea reaction, which can have a temperature change of up to 70 degrees Celsius, induces thermal convection and instabilities in the fluid system. The behaviors generated by this system have been observed in real-life phenomena ranging from carbon dioxide sequestration and atmospheric/oceanic layering to solar evolution.
