Introduction: How to Make a Marshmallow Gun or Marshmallow Shooter
Marshmallow shooter kits with all PVC pieces pre-cut are available in the Instructables store!
This project appears in print as part of Best of Instructables Volume 1.
Instructions are here for the Soda Bottle Safety Goggles.
Step 1: Plans
Get the plans for the gun here or click on the "i" in upper left of the image to get a larger size.
(22 inches of 1/2 PVC pipe (1/2 is a the nominal diameter, its actual outer diameter is closer to 7/8 inch), 2 end caps, 2 three way junctions, and 2 elbows.)
Step 2: Cut the PVC to Length
Cut 1 length of 7 inches and 5 lengths of 3 inches.
Hacksawing is a good choice for this step; here is a How to Hacksaw tutorial.
Step 3: Assembly
Layout your pieces and assemble them. Friction should hold them all together.
Step 4: Test
Put on your safety glasses.
Point the gun in a safe direction. Load a minimarshmallow into the mouth piece, seal your lips to the mouthpiece, and give the gun a quick burst of air.
Yes, the marshmallow does go around all those curves. Pretty cool, huh?!
Keep your ammunition sealed. Dry marshmallows don't work very well.
Clean up your marshmellows when you're done. Especially, don't leave any around roads: they will attract animals to be hit by cars.
