I bought a few packs in "Costco" a year or so back which had built in whistles, the kids love them especially on "special" events, Halloween, Bonfire night to mention two.

opening up and old post i know! but i'm still working my way through the topics never been a fan to be honest i don't like the one use aspect. but they are looking tempting. and just so people know the time it last depends on the temperature, heat speeds up the chemical reaction. and gnole spoke about kids enjoying them,heres an idea not
prepper though but activate cut open and pour into a jam jar and put on the window sill looks good on halloween :p
