chemical hot packs

[gnef]

Hey guys, i am going to be doing a demonstration next week on friday, so almost a week from today. i would like to use the heat packs that are liquid and have a metal disc in them, and when you bend the metal disc to activate it, the pack goes solid and gives off heat.

i've looked at walmart, target, HEB, academy, and walgreens so far, all with no luck. i've found some online and on ebay, but not at very good prices so far, best would be ebay, but i think it should be able to find these cheaper.

any suggestions for local places i could buy these at? or good (read: cheap) online retailers that would be able to ship in time?

thanks!

hm, for this demo, i want them to see the liquid turn to solid and feel the heat. i didn't look in the ski section... hmmmm, i only looked where the other medical things were. i'll take a look tomorrow in their ski section, although, i'm not sure if they even have a ski section... heh.
