Launching jumbo marshmallows sky high is as easy as assembling your own marshmallow cannon. With just a few pieces of PVC pipe and a large bottle, you can make one of your own.

Once you have all your PVC pieces cut to size, fit them together so that they form a rough T shape with your launch tube pointed up at one end and a large mouthed bottle duct tape to the other. Place a marshmallow in the launch tube and jump down on the bottle to watch your marshmallow go.


Stomping on the bottle forces the air (and the marshmallow) out of your launch tube. You can repressurize the bottle for another launch, by blowing into the pipe.
