Intro: Hand Warmer
I made ahand warmer reusing stuff from toys and thing we all have.
This is what you need:
- empty deodorant can
- soldering iron
- copper wire
- tin wires
- silicone gun
- silicone bars
Step 1: Step 1: the Main Structure
You cut the deodorant can the smallest so the battery can fit inside it.
Step 2: Step 2: Adding Wires
You attach wires to the both parts of the batteries, but we have to make the soldering iron hot tip contact with battery terminal for the least amount of time.
Step 3: Step 3: Cardboard
You cut cardboard to the size of the battery, then you cover the baterry so it can fit in the tube.
Step 4: Step 4: the Copper Wires
You take the coper wires from something you have or buy it, and the attach one head of it to the negative cable of the battery and cover all the tube.
Step 5: Step 5: the Switcher
You attach the both cables of the battery to the switcher so it can works. And finally you cover all the tube with scotch tape.
