Learn how to make a marshmallow launcher out of a few household materials! Physics gets fun with this marshmallow launcher experiment that shows how kinetic energy works. Grab your bag of JET-PUFFED Miniature Marshmallows and start learning!

What you need

Balloon

Empty toilet paper tube (just the cardstock tube)

Rubber band

Masking or duct tape

JET-PUFFED Miniature Marshmallows

Stop watch, scale, and measuring tape if you want to calculate the kinetic energy

Make it

(psst...check the boxes next to each step to mark as complete)

Tie a knot at the end of your balloon.

Cut off the tip of your balloon, about 1/3 of the way down.

Position the open-cut end of you balloon around one end of your toilet paper tube.

Secure the balloon with tape.

Load your launcher with a JET-PUFFED Miniature Marshmallow.

Build some potential energy by pulling the knot back on your balloon – then FIRE AWAY! - your marshmallow launcher converts potential energy into kinetic energy and your marshmallow flies through the air!

QUESTION TO ASK YOUR KIDDOS

How can you measure the amount of kinetic energy created?use the equation: Kinetic Energy = ½ x Mass x Velocity(squared)The Mass of a single jet-puffed miniature marshmallow is about 1g.The Velocity of your marshmallow is the distance it traveled divided by the time it took to travel. If your marshmallow traveled 14 meters in 2 seconds, the velocity is 7meters/second.KE = ½ x (1g) x (7)² squared= ½ x 0.001kg x 49 m²/s²= 0.0245 Joules!
