@jadroppingscience: This Sodium Acetate heating pack is reusable and looks awesome to see in action! When the metal disc snaps, it starts the freezing process, that freezing causes the pouch to heat up! #Science #LearnOnTikTok #cool

these are similar looking but completely different phenomena. the sodium acetate is not freezing, it is crystallizing by precipitating out of solution.

All are technically wrong. The heat pack (sodium acetate one) is actually super saturated, but the lack of nucleation sites make it where it doesn't solidify, it why you have to heat it to liquify it again. The second one is the same thing, but in the way most people are introduced to "hot ice" by pouring it on something that can allow for nucleation. The last one is a way to do an actual supercooled water thing, however the problem here can be if there's so much as a single nucleation site, it goes belly up the first moment it can.

how does it freeze if it's exothermic?

I had 1 of these years ago, it was really awesome. Have no idea how it worked. But use to boil it to reset it

Not fake I had a couple of these when I was younger and you put them in the microwave to reset them. I showed one to a chemistry tutor I had who used to be a professor at a university and she couldn’t explain it.

I have those pouches. Pretty cool, just tedious to reset them.

so is it an icepack or a heat pad?
