Marshmallow launcher project

Design Problem

You will apply aesthetic and engineering design principles to design a marshmallow launcher. The launcher must be able to fire from three specific positions for various points. Each individual will be given a period of 30 seconds to warm up, prior to a 120-second period to score as many points as possible. Only two marshmallows can be used during any given testing period.
