![]() Flip over the stack so that the stick you pushed through is now on the bottom Parent: Lay the second notched stick on top of the popsicle stack and wrap a rubber band around the two popsicle sticks. Projectiles (pom poms, ping pong balls, etc. : Take one of the notched popsicle sticks and push it under the top stick of the stack. The supplies are 10 popsicle sticks, a plastic spoon, 3 rubber bands. Let’s pit three basic popsicle stick catapults against each other to find the ultimate popsicle stick catapult design! Supplies ![]() If your goal with a catapult is to stay as far away as you can while still sending an object a great distance with force and accuracy, what makes a better catapult? How can changing your design or materials impact your force and distance? The physics behind a catapult are simple, pulling back on the arm creates stored or potential energy and when you release the arm it converts that energy to motion and flings your object through the air. Catapults have been used as weapons since ancient times, their ability to launch heavy projectiles across long distances made them a key element in warfare, you could attack while keeping away at a safe distance.Īny catapult has three basic parts – the arm (including the bucket), an elastic force (elastic force most often uses tension – stretching force or torsion – a twisting force) and the base or fulcrum (the point where your force and arm meet). Step 3 Gather the other 8 sticks (that do not have a notch). Step 2 Cut a notch (a small triangle) where you had made the marks. Thanks!Ĭatapults are one of my all time favorite STEM projects, whether we are sending out a siege of marshmallow snowballs or launching Peeps into easter baskets, kids are always, always enthralled with a good catapult project. Then place one final popsicle stick under the entire stack in the same direction as the original seven popsicle sticks (see image below). Making the Popsicle Stick Catapult Step 1 Draw a small line on each side of a jumbo stick about an inch from the top of the stick.
