![]() ![]() This simple machine was first used as a powerful war machine to hurl stones, projectiles, and other objects at enemy fortifications. What are catapults?Ĭatapults have a rich history, dating back to at least the 1600s. Whether you’re a teacher looking for an interactive classroom activity or a parent seeking a new project to keep the little ones entertained at home, popsicle stick catapults won’t disappoint. I love creating STEM (or STEAM, if you want to include art projects) activities for my kids and have shared several simple science experiments on this site, including: If you’re searching for some great STEM Activities for Kids and Child development tips, you’re on the right place!

Make a little paper ball and go test your war machine!.Using glue gun, attach the plastic cap to the end of the arm.Use the rubber band to connect the tail and the arm of the catapult.We can make our catapult more durable by attaching a small piece of stick vertically in the middle of that closing stick (like a tail).Glue the third one over those two, so you get a square shape. Glue 2 more sticks on the edges of the construction.Wrap it around all the edges – that’s the arm of the catapult. Take one larger rubber band and use it to attach one stick in the middle.Take 6 sticks and attach them together using 2 rubber bands (on both ends).Watch the video at the beginning of the article for step by step instructions or continue reading… INSTRUCTIONS FOR MAKING POPSICLE CATAPULT: ![]() Unlike the trebuchet which was well suited for launching projectiles over walls, this type of the catapult was best suited for destroying walls since it launched projectiles at lower angles. When crossbar is reached, the arm stops and projectile continues moving due to the force. The launch velocity of the projectile is equal to the velocity of the arm at the bucket end and the angle is controlled by stopping the arm with a crossbar. Upon release, the arm rotates at a high speed and hurls the projectile.
