A toy torpedo to play with underwater at night.
You need:
2 copies of "light-up pool torpedo w- lights"
5 LEDS
1 capacitor
1 battery pack
Calking
Poly Cement or other adhesive to glue halves together
Wire
Solder & Soldering Iron

1. Print out two copies of file
2. Put LEDs into holes
3. Smear calking around LEDs, making hole watertight. (The 5th LED goes into the nose of the torpedo, so you'll have to put calking on the outside.)
