This marshmallow shooter DIY is a childhood must do! It’s a simple kids activity that doubles as a science project and is so much fun you will end up playing with it even after the kids are asleep. True story. ;)

This version of the marshmallow shooter is made with a cake pop container so the next time you have one at a party make sure to save it–you can turn it into hours of fun for your kiddos!

How to Make Marshmallow Shooters

  • cake pop container
  • balloon
  • scissors
  • mini marshmallows
  • rubber bands (optional)
Take an un-inflated balloon and tie a knot in the end. Then cut the bottom half (rounded part) of the balloon off. Stick the open end of the balloon on the bottom end of the cake pop container and you are ready to play!

If you have energetic shooters (like I do!) you may want to use a rubber band to reinforce the balloon. It will help it stay on no matter how hard they pull.


Experiment with your kids to see how changing the amount of marshmallows or force used changes the outcome. It’s a great way to get kids thinking critically and having fun!
