Goals

Build demonstration devices for the MSC Traveling Science Program, which visits schools in Maryland and surrounding states and performs science shows on stage for large audiences.
Improve on older designs, which were difficult to set up and take down, and just didn’t work very well
Keep items compact for easy transport

Design Details

We used simple yet durable materials to make the experiments more relatable, especially since audience members would not be able to touch the experiments.
Designed to be maintainable by Education staff, who may not have mechanical experience
