Link: StarryNight: Paper Circuits and Astronomy for Kids!

To build this, you will need:

  1. Lots of Copper Tape
  2. 3V coin cells [6]
  3. LEDs [about 60 LEDs were used in this project]
  4. Copper Foil [since its conductive both sides, it was used to activate switches]
  5. Long fingernails [optional but HIGHLY RECOMMENDED - to help smooth the bumps while making a circuit or even to fold the copper tape while making sure its still conducting electricity]
  6. Soldering Iron
