Marshmallow Gun

Last updated on June 25, 2018 by Sal Ferrarello

This weekend my oldest son and I built ten marshmallow guns (that shoot mini-marshmallows). The design is similar to that shown at http://www.instructables.com/id/Marshmallow-Shooter/.

The parts are all 1/2 inch PVC (and all unthreaded).

For one blaster:

  • caps (2)
  • elbows (2)
  • tee joints (2)
  • tube 12″
  • tube 6″
  • tube 3″ (5)

For the tubes, we purchased three ten-foot tubes, which was enough for 10 guns.

The only tool we purchased was this BrassCraft 1-1/4-in PVC Cutter, which worked great and can be used indefinitely.

Technique

Originally, I was loading the mini-marshmallow in the barrel, which was a mistake. The marshmallow should be loaded in the mouthpiece. Despite my initial skepticism, this is by far the best way to load the marshmallow.

    It starts innocently with marshmallows. But they’re just the gateway. Before you know it it’s potatoes and then pumpkins.

      Marshmallows are the low-key version, as opposed to when we were teenagers and built a potato gun (full disclosure to other readers, it was Mike’s idea and I’m forever grateful). Based on this timeline, I’m not sure when pumpkins come into play – perhaps once our respective children are old enough we can launch them as part of a “science project”.
