I made a fun glove that lights up every time you make "the gun" sign with your hand. (thumb and forefinger pointing outwards like a gun)
Step 1: Basic Schematic
Step 2: The Guts
Instead, I used electrical tape to insulate the battery and connect the wire snuggly.
Then, I simply sewed the wire into the glove. I would have preferred to use conductive thread, but I didn't the have time to order it online and I was too shy to ask Becky if I could barrow some of hers (I'm kind of a dork, I know).
Step 3: The Switch
I flattened out the wire to make contact a little easier.
Now everytime one connects his ring finger to his palm, the LED will light up! Yay!
Step 4: Off
Step 5: BANG!
You can use this same glove to light the LED using any hand sign that brings your ring finger to your palm.
My favorite choice was of course "the gun".
