Step 1: Materials
100 CR2032 3V Lithium Batteries
100 "Super-Brite" LEDs (50 Red, 50 Yellow)
50 Magnets (1/2" Dia x 1/8" Thick NdFeB Disc Magnet)
Packing tape Roll
Here is what I have concluded about my first set of ten throwies:
-The magnets seem to loose a little of their strength when they are attached to the battery.
-The "Super-Brite" LEDs ARE way bright but,
-My LEDs were not diffused, so they don't "glow", they just "point-shine".
-Packing tape is hard to strip down into battery-width strips.
