Pocket Hand Warmer

Hey!

Where I'm from we have pretty cold winters, and I always wanted to have something that will produce heat and keep my hands warm. So as necessity is moter of "invention" I made this very simple heater that runs on a 9V battery.

I hope you like it and if you want to see more videos of this kind, check out my channel :)
