Sound Activated Condom Lights. Must see the video ending :)
Step 1: Supplies Used,
2 Blue 5mm LED's 3.7 volt 2600mcd
2 5mm LED Holders
Heat shrink wrap
Some thin gague wire. I used an old phone cord.
2 tops off a Gaterade bottle
Step 2: Putting It Together
Install the LED's into the holders, and attach the holders to the bottle tops.
(Note, the longer leg on the LED is positive, so hook your wires up accordingly.)
Add some thin wire to the LED's(I use an old phone cord), and attach the wires to your speaker wires. This will only work on amplified speakers, or speakers that plug into the wall.
