How to keep the snake heated during power outages?

[Pythonfriend]

someone mentioned disposable heat packs.


but noone recommended re-useable heat packs so far They are soft, made of silcone, filled with a liquid and have a little metal chip inside that can click. You click it, it immediately starts to crystallize and reaches the melting point of the stuff inside, around 55° celsius. They keep the temperature up for hours, until they are fully crystallized, if you wrap them in tissue so that they are a bit isolated they keep up the heat even longer.

afterwards you can put them in boiling water until all the stuff inside is completely dissolved, then they are reset and you can store them for the next use. so you can use them again and again without producing waste.

they come in all shapes and colors, for example:

i like them because they have a maximum temperature around 55° celsius / 130° fahrenheit and wont go above that, but will keep that temperature, and because they dont produce waste.

p.s.: i wonder how often people get snake shipments with these inside and throw them away because they dont realize this
