i hate the fact that you have to boil it to deactivate it... i'd rather get the zippo hand warmer.. its gives you 24 hours of heat on only .4oz of lighter fluid..
It's sodium acetate. They do various demonstrations with supersaturated solutions in chemistry. The heat lasts about half an hour, which is much less time than disposable hand warmers. You can repeat the process many times. Boiling the warmer dissolves the crystals back into its liquid solution.
I assume this means that after you have used it once you must heat it up manually if you want to continue using it as a warmer. So you only see this chemical reaction once (the first time you use it) and never again?
no, wen the cemical reaction happens, the whole thing goes hard so u cannot heat it again useing the metal piece, need to boil it so all the cristals can disappera so then u press it again and it works.
the liquid was Supersaturated (sodium nitrate.. acetate??) so when we pop the coin, some of it will break out and start the reaction, the heat come out when the reaction take place made the heart warm up <3

I'm not sure if I should smile or cry because I understood what they said, even though I've never taken any japanese lessons.

@jessymessy65 its a hand warmer, when the liquid crystalizes it creates a lot of heat.

the cemical reaction generates heat and become solid crystals not ice

Soo when you boil it do the solid crystals go back to a liquid so that you can watch the chemical reaction all over again?

does it become a solid?

I used to have a hand warmer just like this (different brand) and it got really hard after I used it.

@watermelontwister thats why you boil it

after it has been completely cooled off you wrap the heart around with a towel or cloth and place it in boiling water for approx. 10-20mins.

How long does it last? The ad says it is semi-permanent, which is almost like saying nearly later.
