Before I start googling, does anyone have links to an ice pack that you twist/snap etc like a snaplight that then becomes cold as an icepack ?
The opposite of chemical hand warmers.

Not the ones in my first aid kit.. It's a bag of liquid with another 'bag' of different liquid inside it that you rupture without puncturing the outer bag so the 2 chemicals mix and cause a cooling effect by some kind of chemical reactionAccording to the ingredients on the one we have in the scouts' first aid kit its just a bandage soaked in some volatile alcohol (isopropyl I believe)
Presumably it just works by evaporative cooling
Hi Scots, how did the cool packs work? do they keep stuff cool for very long? In my experience of using them for sports injurys they dont last long but I was wondering if they worked longer i conjunction with a cool bag or something similar?
Cheers
