Heart Hand Warmer to use again and again
It’s the time of year where, if you spend a lot of time outside doing outdoor activities (or if you have to watch someone else do those outdoor activities) it’s pretty likely that your hands will get cold. Those chemical hand warmer packets are nice, but you only get one use out of them.
The Heart Hand Warmer is a red, heart-shaped chemical hand warmer that can be used over and over again to keep your hands nice and toasty. On the inside, there is a small metal disc that when moved back and forth a few times in the clearish gel will turn the gel opaque. The opaque gel is what warms up the hand warmer using some nifty chemical reactions. ThinkGeek explains it as such:
[T]he pretty red gel is a supersaturated solution. Bending the disc starts an exothermic crystallization of the gel (i.e. it goes opaque and gets hot). And when it loses its warmth, all you have to do is wrap it in a towel and throw it into boiling water for about 15-20 minutes and the Heart Hand Warmer resets itself. Once it cools off from its boiling bath, it is ready to be used again.
As an extra added bonus, you can chill the Heart Hand Warmer in the fridge for a few hours to use as an ice pack of sorts. No boiling required to reset the hand warmer to it’s ready state. Pick one up for $5.99.
Dimensions: approx 3.75″ wide.
