![]() Put three end to end then put two right on top of them. We use five popsicle sticks and this picture shows you how to arrange them. Here is the completed triangle, now all that remains is to tape all the shapes together. Now lay one triangle down on the table and splittling the legs on the two you taped together slide them right over the one on the table. Our Geodesic triangle is going to tape shape now. The red arrow shows the side that I have taped together. Now hold two of the triangles together side by side and tape them only on one side. Do this process two more times so you have three triangles. Now fold the length of sticks into a triangle and tape the end together. Use at least three wraps of tape at the joints to make it nice and strong. Now, as in the photo shown below, place these three popsicle stick assemblies end to end and then tape them together. This is the basis for your first triangle. Do at least two full revolutions of the tape. Now you can wrap the tape around all three. ![]() Place a third stick on top of these two sticks, right in the middle. But just press the sticks down firmly on the tape, don't wrap it up yet. You lay out your tape with the sticky side up then place two sticks end to end right on it. Here is the basic process for taping sticks together. Here is what you need to make this Catapultģ2 Popsicle sticks, some masking tape, pencil, rubber band, scissors, X-acto knife (optional), piece of paper about 6 inches square. 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 ![]() Have a look and give it a try! Here we go.Ĭheck our Innovative Collection of DIY Catapult Models using variety of materials 1.Hi, Thanks for visiting my website. In this post, I have included 10 different methods of making mini catapults right from your home or school. Let us begin with some STEM challenge activities for kids that allow them to create homemade mini catapults in an excellent way. Do not worry! Our homemade medieval rocket launchers are not dangerous but still recommend to supervise the children while making the beautiful and creative mini catapults, medieval rocket launchers. Let our kids learn this physical science activity hands-on and in an easy way. Using the same engineering design process, we are going to make our own mini-versions of catapults in different methods. The best process to make these amazing catapults is ‘The Engineering Design Process’, which our ancient and modern engineers utilizes everyday till date. How does a catapult work? Catapult stores up potential energy and releases all at once as kinetic energy which makes a projectile or object throw far away (much further than a human could alone) through the air to the fixed targeted area. Today, we are going to turn our young scientists into little engineers! Yes, we are going to combine STEM, physics, and craft in a surprising way of creating “Catapult”.
