1

Make the head

  • Roll the red play dough into a ball to form the caterpillar’s head.
  • Use the green and yellow play dough to make the eyes.
2

Add the insulator

  • Place the card circle to the back of the caterpillar’s head.
  • Roll some of the green play dough into a ball, so that the ball is the same size as the head.
  • Place the green play dough ball to the card circle.

Things to know

The card will prevent a short circuit. You could use any insulator here - plastic, insulating dough, a piece of rubber.

Make the body

  • Roll two blue play dough balls.
  • Roll two green play dough balls.
  • Place these play dough balls behind the green play dough ball to make the body. 

Things to know

Make sure the green and blue play dough balls are all touching each other BUT not touching the red caterpillar head.

Add the light

  • Place the long leg of each LED into the caterpillar’s head – ouch!
  • Place the short leg of each LED into the first dough ball of the body.
5

Power it up

  • Make sure the battery pack is OFF.
  • Insert the red battery wire into caterpillar’s head.
  • Insert the black battery wire into the first dough ball of the body.

Things to know

Make sure the red battery wire is placed into the caterpillar's head as the LEDs will only light up when the long leg is connected to the positive (red) end of the battery.

Shine bright

Turn the battery pack ON and watch your caterpillar’s eyes light up.
