Marshmallow Guns

One Saturday morning, gently wake up the kids and explain to them that it is time for war. Marshmallow war! Tell them that they need to build their own weapons of mass destruction or face certain annihilation.


It’s really easy to build your own marshmallow guns. The kids will have fun piecing together all the parts. Here’s what you’ll need:

  • 22 inches of 1/2 inch PVC pipe
  • 2 end caps
  • 2 three way junctions
  • 2 elbows
  • A hacksaw to cut the PVC pipe
  • Permanent marker

This Instructables site has a good page that describes how to build a marshmallow gun. Have the kids write their names on their guns.

Puffy Ammunition

Use mini marshmallows. Be sure to keep them dry so that they don’t get stuck in the pipes.

You don’t have to buy bags of marshmallows. You can give each warrior about 20. Then after they shoot them, they can pick them up and shoot them again. This way you’ll minimize the mess a bit.

The Great Battle

Before the great battle starts, have the kids put on sunglasses, ski goggles, or their snorkeling goggles. Anything to protect their eyes … just in case.

To load the guns, place the marshmallows in the end that you blow into. Give it a good puff of air. You’ll be surprised how far and accurately the marshmallows fly.

It’s good fun!

Last Bit of Advice

Marshmallows will be all over the place after the great battle. Have a few prizes available and make a game out of picking up the marshmallows. If you have a little scale, you can tell the kids that whoever picks up the most marshmallows will win a prize. Have a few second and third places prizes available too. This way the kids will enjoy cleaning up.

Have fun with the kids!
