- Cthulhu_ 9y agoNeat. I have / used to have a pair of 'hand warmers', plastic bags with a fluid of sorts and a copper (?) coin you can 'flip over', the click / shock causing the fluid to crystallise and generate heat. Those can be reused too by putting the (crystallised) bag into hot water for a bit.
- CryptoPunk 9y agoAre the heated cans sold in the Japanese vending machines self-heating cans? EDIT: According to this, the Japanese ones keep the cans heated: http://www.vendingmarketwatch.com/article/10273776/hot-can-vending-initiatives-emerge-in-the-us http://www.vendingmarketwatch.com/article/10273776/hot-can-v... >>Proprietary heating technology >>Unlike hot can drink machines in Japan, the Starbucks machine does not keep the steel cans heated. Instead, the container heats after the customer makes a selection.
