This exhibit is composed of a series of peg walls, boxes, and tables. Visitors are able to use construction sets including pulleys, stretchy bands, struts, bars, joining plates, pins, and straps to construct complex structures. A central component of this exhibit is a vertical build station, which can be a large peg wall or a wall with four mechanisms incorporated into it that perform the following

 

Functions:

  • Windshield Wipers: Demonstrates how rotary motion is translated into an oscillating motion

  • Cam: Demonstrates the motion of a ball being pushed using a cam follower riding on an obliquely shaped cam

  • Piston: Demonstrates how rotary motion is translated into linear motion.

  • Geneva Gear: Demonstrates how a constant rotary motion is translated into an intermittent rotary motion.
