This group of clever friends built what I believe is the world’s first four person Marshmallow Shooter. The Marshmallow Shooter is one of our classic How-Toons projectsMake Vol. 2. It’s made from a few pieces of PVC pipe, and it sends mini marshmallows flying through the air. I’d say that thousands and thousands of these fun toys have been built over the years, but leave it to the folks in Detroit to completely innovate it!
