Drum Machine

This device is the centerpiece of Contraptions A to Z. Visitors create their own percussion ensemble from six horizontal rows of instruments-- dombeks, cowbells, cymbals, congas and other multicultural instruments. The drumsticks are on chains and pass in front of the instruments and mechanical switches that visitors can turn on or off. In the on position the drumstick is tripped, playing that particular instrument on that beat. A single reset lever knocks all the switches to the off position, giving the user a chance to create a completely new rhythm pattern.
