In this design challenge activity, learners build a device to carry a Ping-Pong ball from the top of a zip line to the bottom in four seconds (or less!). Learners follow the design process to build the carrier that slides quickly down a zip line string, figure out how to keep something balanced, and identify ways to reduce friction.
