What you need

  • Purple conductive dough
  • Yellow conductive dough
  • White insulating dough
  • 1 LED
  • Battery holder with 4 AA batteries

Steps

  1. Long rolled strip of purple dough next to yellow and white dough

    Make the outside of the bulb: roll a piece of purple dough until it is long enough to make the bulb shape.

  2. Purple dough bulb outline with a closed base

    Make the base of the bulb with small pieces of purple dough to close the open end of the bulb shape.

  3. Yellow and white dough filament inside the purple bulb

    Make the filament from yellow dough and white insulating dough. Make sure the yellow pieces only touch the white dough.

  4. LED pushed into the two yellow filament pieces

    Push the short leg of the LED into the yellow piece on the left and the long leg into the yellow piece on the right.

  5. Dough light bulb wired to the battery holder

    Push the battery holder's red wire into the yellow piece on the right and the black wire into the yellow piece on the left. Turn on the battery holder to light up your light bulb!
