It would be really cool to make a mini terrarium out of a jar or something and using a Peltier device to control the atmosphere inside. You could set up an Arduino with a small thermostat so that it reverses the charge to the Peltier device depending on whether it needs to be heating or cooling.

There would be some messing around involved to get that to work but it could be a fun project!
