Kids and family play with motors and batteries to create a personal totem.
The totem is set alive when the kids used their fingers covered with a small round sticker of aluminum tape to close the circuit. (The participants switch on and off the circuit by putting their aluminum covered finger in the middle of open circuit module.)
Tips: suggest to the participants the inclusion of the open circuit module, as we noticed that kids were even more impressed by their own creation when they could making works with their finger.

Kids and family draw circuits on the floor using 3 stripes of aluminum tape. They then put the battery and LEDs modules on top of the aluminum stripes, at the corners of the drawing. The drawing light up!
Circuits add up on the floor, and can be reused or simply serve as traces of previous participants' activity.
Fun: One kid drew a simple car with the diodes being the back and front lights.
