![]() ![]() The Geodesic dome is a series of triangles that are formed together so the triangles are now in three dimensional shapes like this catapult. It is what is used to make geodesic domes which is what Epcot center is made out of. ![]() I have this project in a Microsoft Word Document if you need to print it up: How to Make a Popsicle Stick CatapultĪ little About the Triangle - The thing that makes this catapult so easy to build yet so strong (You can use quite a potent rubber band on this catapult and fire your projectiles a long way) is the use of the triangle which is the strongest geometric shape and is used in everywhere in architecture. You can see the project and the game here. ![]() It is part of the Storm The castle catapult game. Note: Some people want to build this version of the popsicle stick catapult. Want to see a video of it in action: The Popsicle Stick Catapult firing off! (Quicktime MOV) This catapult is pretty strong and really fires a projectile so in order for the whole thing not to go flying I had to nail it down. I used a strong rubber band so this catapult actually fires a little projectile quite a long ways! Thirty feet in the air! And you can make adjustments to this and get it to fire further! It also shows you a fundamental concept of engineering - the strength of the triangle. It takes about thirty minutes and it uses 32 popsicle sticks, some masking tape, and a rubber band. This catapult project is an easy and fun project. My name is Will and if you have questionsĬontribute projects or ideas you can contact me How To Build A Catapult We love this easy LEGO Catapult.Hi, Thanks for visiting my website. ![]() More Catapult Design IdeasĬan you build a giant catapult? We used this one to launch tennis balls over a net. If you want to learn more about Newton’s Laws of Motion, try our film canister rocket. The further you push the catapult arm down ( which takes more force from you ) the further the ball will travel. If you push the catapult arm down further you are storing more elastic potential energy which means more kinetic energy is transferred to the ball when you release it. Catapults and conservation of energyĪ lolly stick catapult demonstrates energy being converted from one type to another ( potential to kinetic ) and transferred from one object to another ( catapult arm to the ball ). When you pull down on the catapult arm, elastic potential energy is stored, when you release the catapult arm the potential energy changes to kinetic energy ( energy of motion ) which is transferred to the object which then flies through the air. Newton’s First Law states that an object stays at rest until a force is applied to the object. See who can score the most with a set number of balls. Set a challenge to find out how far you can make a ball travel! Add some mathsĬreate a target with different numbers in different areas and use the lolly stick catapult to fire balls at the target. Investigate to find out if a heavier ball travels further. Try adding extra or fewer sticks to the central part of the catapult. Remember to only change one variable at a time Change the design Popsicle Stick Catapult Investigation Ideas Experiment with your table tennis balls.Attach a milk bottle top using double sided tape or strong glue.Twist another elastic band around the bottom of two sticks as you can see in the photo.Tie an elastic band around the middle of the cross.There should be more lolly sticks on the end you want to use for the milk top. Place another stick above and one below the stack of 7 so they make a cross shape.Twist an elastic band around each end to hold them in place. Start with about seven popsicle sticks and place them on top of each other.Tape measure – optional How to make a lolly stick catapult Popsicle Stick Catapults What you need for a Popsicle Stick Catapult ![]()
