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?

  • Get NaAcetate pads from Hotsnapz-com

    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.

  • But How"

    To reset them? How again to take the reaction? What about substance in the klips?
    However - 5 Stars!!

  • only once?

    What do you mean "Hot Ice" can be used only once? You simply heat up the sodium acetate in a pot or pan and pass it through a filter.

    • Camping Stores

      He said you could find them at Camping Stores, and the only major one I know of is REI, although I remember seeing those at a Sports Authority store several years ago (although I don't think they were the ones he was using.
