Popsicle Stick Catapult

Catapults were first used in Greece at around 400 BC. Although they are much larger than this Popsicle Stick Catapult version, the concept is the same. Catapults were used in war because of its power of destruction. This version is super simple to make and only needs a few supplies that you may even have at home already. Try this fun science project for preschoolers, kindergartners, grade 1, grade 2, grade 3, grade 4, grade 5, and grade 6 students.

Catapults for Kids

The first thing we did is stack 5 popsicle sticks on top of each other and secure with rubber bands on each side. Next, place a popsicle stick perpendicularly on top of the stack of popsicle sticks and one on the bottom. Secure these on one end, making a v shape around the stack. Next secure with crossing rubber bands. If you can see from the picture, we made an x with two different rubber bands in the center.

Next we hot glued a water bottle cap to the top popsicle stick on the opening of the V.  You’re ready for catapulting.

Amazing, easy to make craft stick catapult physical science project for kids

Craft Stick Catapult

You can shoot a variety of things from your craft stick catapult from mini marshmallows, pompoms, small candy, etc. We decided to shoot marshmallows and make it a marshmallow catapult like one of our favorite books – Marshmallow Incident

I was super surprised how far the marshmallows flew. Also how high they went. I know catapults were powerful back in the day, but I had no idea how powerful this little one would be.

Physical Science Experiment for Kids

So now that you know this will be a fun project with a little history mixed into it, did you know that it is also a lesson in physics?

The science behind a catapult motion is that when you bring back the top of the catapult, with the marshmallow ready to fire, you are creating stored energy. This stored energy is what is used to hurl the piece (the marshmallow). This uses both tension and gravity for this motion. Super fascinating, isn’t it?
