For example, what about using gummy bears to make swimming pools? Meringue to make rocket insulation? Or even chocolate to make a bridge?Through these whacky combinations, Roma reveals the secrets of how materials work, and why engineers don’t normally attempt such stunts and stick the materials they know and love.This is a theatre event for children and adults to enjoy together.
