I have got a pair of those re-usable hand warmer things - the liquid filled ones with the metal switch inside them. When you press the switch, the liquid turns sort of solid and heats up to keep your hands warm. It tells you to place them in boiling water for a short period in order to re-use them. I assumed that they would go back to the way that they were when I first bought them, and you would press the switch again ito get them to heat up, but instead, it turns to liquid again at first, but seems to go solid again as they cool.
Am I doing something wrong? Or is the boiling water simply intended to heat them up to be re-used there and then. Does anyone know if there is a way to reuse them by pressing the switch to activate the heat?
