Marshmallow Shooter

This Demonstration is included in a bundle of 101 Science Demonstrations & Experiments. You can find this bundle here in my TpT Store. These exciting demonstrations use mostly inexpensive materials that you can find around your home or can be easily purchased. I show how to run the demonstration, give helpful advice and explain the science concepts behind it. Many of these demonstrations can be turned into STEM projects for your students.

Materials needed:

Sturdy Paper Cups
Mini Marshmallows
Balloons
Duct Tape

Directions:

  1. Cut a large hole in the bottom of the cup.
  2. Take your balloon and tie a knot in the open end. Cut the top 1/3 of the balloon off.
  3.  Stretch the balloon over the top of the cup, folding it over the sides. Pull the knot through the hold.
  4. Use the duct tape to secure the balloon on the sides of the cup.

The Science Behind this Experiment:

How does a marshmallow shooter work? If you stretch a rubber band, it will have elastic potential energy. As you let it go, that potential energy will transfer into kinetic energy, the energy of motion. In our shooter, the balloon is acting like a rubber band. When you pull the knot on the balloon backwards, it creates potential energy, which then transfers to kinetic energy as you let it go, sending the mini marshmallow flying!
