T-Shirt Launcher

A photograph shows three students launching a folded-up t-shirt from a big y-shaped device made of PVC piping that looks like a big slingshot.Your design challenge: To find a way to get school t-shirts up into the stands during sporting events.

Students are challenged to find a way to get school t-shirts up into the stands during sporting events. They work with a real client (if possible, such as a cheerleading squad, booster club or band) to determine the requirements and constraints that would make the project a success, including a budget constraint. They think “outside of the box” to come up with lots of ideas. Then they mock-up small-scale model(s) of their best, most feasible ideas for testing, before making full-scale usable devices that they further refine and then demonstrate and deliver to the client. They use the engineering design process to complete this challenge.
