Step 4Solder the LEDs!

Solder the LEDs!

I used 5 leds in each red, green, and blue. They are all 5,000 or 6,000 mcd (brightness). I then soldered them together and hooked them up to two 9 volt batteries. Only the red LEDs needed a lot of resistance (they are only 2v). Then, be sure to insulate the wires before getting them near aluminum foil.
