Inventive Arm

With modular wooden pieces, wire and rubber bands, construct a hand with fingers. The parts will work in a dozen basic configurations.

Test your design: Retrieve a lifesaver, a penny, and a marble from a cup. Pick up a marker and draw. Pop a balloon. Propose your own challenge. Invent games that two hands can play.

Outcomes: Each task may require specific adjustments. Some hand configurations are more versatile than others. Discover the interplay between tasks and design.
