The "Hot Ice" reaction is amazing, but messy and can only be used once. A great reusable alternative of a supersaturated solution are chemical hot packs that you can buy from a camping store. They contain a solution of sodium acetate that can be reset in less than an hour. They are also good as hand warmers, but why would you buy those?
I get them from Hotsnapz-com and also use them for science class instruction. The reaction is reversible by putting them in boiling water. (Reaction reverse >160F) I've gotten good deals on larger quantities by calling. Based on Supersaturated solution of Sodium acetate salt and water. Clicker just initiates a nucleation site for the crystals to start forming in the supersaturated solution.

However - 5 Stars!!
