This game of skill will test the steadiness of your hand. When you try to trace the outline of the convoluted wire with the looped handle, the slightest contact will sound the alarm. You can change the challenge by modifying the shape of the wire. The variable resistor can be used to change the pitch of the sound.
Requires soldering kit and a 9 V battery (not included).
Dimensions (approx.): 3.3 x 3.0 x 4.7″ (8.5 x 7.6 x 12 cm)
