Barkell Elementary School

Fourth-grade students at Barkell Elementary designed their Operation game pieces and form in Tinkercad, 3D-printed them and then designed a circuit with help of conductive aluminum foil. When the Operation tweezers touch the edges covered with aluminum on the edge of the holes in their frame, the circuit is complete and the light goes on.

Are you a surgeon with a steady enough hand to remove the piece from the patient without completing the circuit and lighting the light?
