Experiment with different distances, and even different amounts of popsicle sticks in the stack, to see what works best. When the stacked popsicle sticks are farther from the elastic on the spoon, the objects tend to be shot straight up in the air. The closer they are to the elastic, the farther the projectile will go. You can also change the angle of the catapult by moving the stacked popsicle sticks closer to the elastic on the spoon. If your spoon is flexible enough, pull it right down to the table before releasing it to get more speed. Students in AlphaJump present their ideas at the annual Catapult competition. Try pulling the spoon down at different angles. enhances student enrichment while fostering an interest in entrepreneurship. Then gravity plays a part, bringing the load back down. Releasing the arm changes the potential energy to kinetic energy, sending the load flying. Pulling down the arm of the catapult is force, which creates potential energy. An object stays at rest until an external force is applied. How levers work can be explained using Newton’s Laws of Motion. You push the arm (plastic spoon) over the fulcrum (popsicle sticks) to launch the load (tin foil balls, or whatever you choose). These popsicle stick catapults are a simple machine called a lever. You definitely want heavier duty rubber bands for this experiment. We first tried using rainbow loom elastics, but they were too loose. If you don’t have asparagus elastics, thicker elastics, like size #64 rubber bands, will work the best. We used the elastics that were around our asparagus bunches, and they worked perfectly. Make a prediction about which object you think will fly the farthest! Which elastics are best for a popsicle stick catapult? Try paper balls, marshmallows, eraser tops, bottle caps, or pom poms. ![]() But you can send any object flying with these catapults (within reason!!), which makes them so much fun. Objects with a bit of weight to them, like a ball of tin foil, are the perfect projectile. ![]() What type of projectiles work best in popsicle stick catapults? The full printable instructions are at the end of this post, but here’s a list of products on Amazon that are similar to the supplies we used: The Catapult Network supports businesses in transforming great ideas into valuable. If you use these links to buy something we may earn a small commission which helps us run this website. A Catapult is where the application of research is accelerated. As you can see, the target doesn't need to be pretty.Looking for more fun ideas? Here’s some of our favourites: All you need is a large piece of paper and a pen. We set up this simple target game in no time with only two items. Once your child has got the hang of their new toy and is catapulting objects all over the living room, take a moment to redirect their attention to some more structured target practice.

Place a soft item ( such as a pompom) into the bottle cap. ![]() Glue the bottle cap to the top of one end of the board. Tape it to the bottom of the board in the center. We had a piece of foam core board left over from a package and attached a length of cardboard with duct tape to the top of it.Īlternatively, you can tape several layers of cardboard together, or use a thin piece of plywood.Ĭut your tube the width of your board. For the diy catapult board: You want something that will not bend at all.
