On the forums at Crazy Builders, a maker named “Technician” has posted a series of videos and photos explaining how his quick dump valve high-speed marshmallow cannon works. The cannon is made from some PVC pipe, a propane camping lantern bottle, and some 1″ pipe. It’s a scaled-down version of a larger T-shirt cannon he built for a competition.
