This helps you aim the cotton ball forward. After making the first model, encourage kids to make their own 'improvements' by handing them additional popsicle sticks, spoons, and glue sticks (for the hot glue guns). Pushing your six sticks the other direction creates a greater angle between the launching stick and the base. This results in a cotton ball aimed more upward than forward. Moving the stack of six sticks closer to the launching cup makes the launching stick lie flatter. In the case of your catapult, the cotton ball probably flew higher and farther. Bending farther means more energy gets stored in the stick, and when you let go, all this stored energy is converted into energy of motion, so the cotton ball flies through the air at a higher speed. To assemble the catapult, create two equilateral triangles using popsicle sticks and secure them at each vertex with rubber bands.

Maybe you felt you needed to exert more force or work harder to bend the stick farther. Pushing the stick down farther takes more effort from you. The trebuchet is a medieval device, not unlike a catapult, that was used in warfare to hurl damaging objects from afar into areas that were otherwise inaccessible, such as over castle walls and into forts. Most of this energy transfers to the cotton ball, which shoots through the air. Make a desktop catapult out of popsicle sticks. When you let go, this energy is released and converted to energy of motion. Gather your popsicle stick catapult supplies. So, here’s some simple steps to making your own today. My 10-year-old loved them just as much as my four-year-old. Plus, it’s the perfect craft for kids of all ages. When you bend your stick, you load your launching stick up with energy. Put your catapult in an open area with a sturdy, flat surface such as a table or an open space on a hard floor. These catapults only take minutes to make but my boys played with them for hours. Step 2: Lay 1 Popsicle stick along the back of the spoon’s handle and attach it using a rubber band at the end. Step 1: Stack 5 Popsicle sticks and tie them together with a rubber band on either end. Do you get similar results each time? Is what you observe what you expected? Can you explain why?ĭid you see your cotton ball fly higher and farther when you pushed you launching stick farther down? You’ll need: 7 wooden Popsicle sticks, a plastic spoon, and a handful of rubber bands.
