Start with one of the suggestions below, but get the kids involved in finding soft and safe alternatives. The good news is that modern life has provided many alternatives to the medieval rock. The three primary energy storage mechanisms are tension, torsion, and gravity (Newton’s laws) Together, Katapultos means “shield piercer.”Ĭatapult physics is basically the use of stored energy to hurl a projectile (the payload), without the use of an explosive. “Catapult” comes from two Greek words, “Kata” which means downward and “pultos” which is a small shield. Catapults have been used since ancient times all the way to World War I. They proved themselves very effective as siege weapons and invaluable on the battlefield. Catapults were first invented to hurl projectiles farther than any human could. The science behind a catapultĮven though your kids will see catapults as a fun activity, there is a lot of science involved with the laws of motion. Push down on the spoon and release to launch an object from catapult. Wrap a rubber band around all of the craft sticks to hold the catapult together. Place the stack of 5 craft sticks between the lolly stick and spoon. Separate the spoon and the popsicle stick. We prefer a wooden spoon to a plastic one for our popsicle stick catapult design as it gives without cracking making for a better “fling”. How to make a catapult using popsicle sticks ice cream stick art and craftMaterials :10 popsicle sticksRubber bandPlastic bottle capHot glueThanks for watc. Pull the 2 popsicle sticks apart and wedge the stack of 7 popsicle sticks between them. Make a stack of 2 popsicle sticks and use a rubber band to tie them together on one end only. Stack 1 popsicle stick and the wooden spoon together and wrap a loom band around the very end. Make a stack of 7 popsicle sticks and use rubber bands to tie them together on both ends. Use 2 more rubber bands to secure the sticks together. Then, take 2 more popsicle sticks and lay them on top of the marshmallow, so that they form a cross. Next, take your marshmallow and place it in the middle of the rectangle. Stack 5 lolly sticks together and wrap a loom band around each end Use 2 rubber bands to secure the sticks together at the corners. It flew the distance easily, but not once in my nearly thirty tries did it land on my sheet of paper.Īll in all, I found this project extremely interesting informative, and fun, causing it to be my favourite one so far.How to make a catapult out of popsicle sticks Thankfully I had a drop more of glue in my hot glue gun (phew!), so I glued on the “bottle cap” to my catapult.Īfter a short break to eat some of my ammunition (red Haribo gummi bears are delicious, but the orange ones are disgusting!), I decided to test out my catapult from about five feet away from my target. Easy make catapult Dan Snow tries out a working mangonel - a siege weapon that utilised rope under tension to fire shots up to 100 metres. Stack 1 popsicle stick and the wooden spoon together and wrap a loom band around the very end. Stack 5 lolly sticks together and wrap a loom band around each end. After securing that loop onto the top of the circle I had something that looked like a cardboard bottle cap. How to make a catapult out of popsicle sticks. Using hot glue I secured the ends of the strip together, creating a circle. I found a small piece of cardboard and cut out a small circle and a skinny strip. I couldn’t find a bottle cap or anything else that was small enough, but that wasn’t a big problem. To make your own popsicle stick catapults you’ll need: 8-10 popsicle sticks 6 small rubber bands small objects to launch 1) Start by rubber banding 5-6 popsicle sticks into a stack. I quickly realized that I had forgotten a key part of my catapult a container to fix onto the top of the swinging arm! Without it, my gummi bears would have slid right off. The ideas are plentiful My daughter had the most fun seeing how far she could move her bucket away and still get her dime into it. I added on the swinging arm and grabbed one of my gummi bears, ready to test my catapult. It took about 30 minutes to construct my wooden frame. Attaching popsicle sticks with only rubber bands was difficult because achieving the desired angle took upwards of 3 or 4 minutes. Take the fulcrum and wedge it between the two sticks. Stack 2 jumbo popsicle sticks on top of each other and secure with a rubber band, approximately one inch from the end. Calvert sent to us, I had a basic idea of how to use rubber bands and popsicle sticks to create my catapult. Stack 5 jumbo popsicle sticks on top of each other and wrap each end of the stack with a rubber band. We got to build real, working (mini) catapults!Īfter watching one of the video lessons Mr. Before last week I knew that I used levers in shovels, scissors, and other devices, but I had no idea that there were different classes of levers or that there is so much science behind them! What was even more interesting and fun than the lesson though, was the project.
