Drill in another to the slinger piece of wood (the end of the 28-inch piece of wood), with the hook facing the end.Ĭustomise the catapult to whatever design you like. Read more about the science behind the catapult and simple ways to create a catapult science experiment below STEP 3: Test and measure how far each item goes when flung from the catapult. Make sure the 28-inch piece of wood is central and in line with the angled piece of wood above.ĭrill one eye hook to the bottom of the angled piece of wood – make sure it is facing the ground. STEP 2: Hand out supplies to each individual or in small groups, and build a Popsicle stick catapult following the instructions below. The dowel should then be inserted through the other side of the base. Grab the dowel or pipe, and insert it through one side of the base, and then through the hole of the 28-inch piece of wood, so that it is central to the dowel. Drill a hole through one end, through the side, all the way through, and make sure the hole itself is one-inch wide. Grab the 28-inch piece of wood, and lay it out flat. Additionally, parents can opt for a DIY Plus subscription that allows kids to join 100+ live interactive workshops every month, share their creativity by posting their content onto their profiles, interact with 1000s of kids from across 170+ countries, participate in. This will provide strength and support for the catapult. The DIY app is free to download and offers access to 5000+ DIY projects and videos across 150+ skills to all free users. Make sure the plank lines up and that it lies attached on the inside.įrom there, take the third 14-inch piece of wood, and cut two angles on it so both ends can be drilled and attached to the base and the horizontal plank above. Next, take the 10.5-inch piece of wood, and drill it to the top of the 14-inch pieces to form a horizontal line. Screw together the two 14-inch pieces of wood to the dints of the two 24-inch pieces of wood from the base. Then, cut half way in and chisel any excess word out. With the base in place, next up, take two 14-inch pieces of wood, and make a mark 2.5 inches from the edges. Make sure that the 7.5-inch pieces are on the inside and that the 24-inch pieces are facing outwards, so that the marked areas are on the outside. Next, make a base by screwing the 7.5-inch-long pieces of wood to the two 24-inch-long pieces of wood at the corners. Use a chisel, and hammer out the excess wood. Then, saw out the gap between the marks, sawing down only halfway, so there’s a thick base. ![]() Measure down 5.5 inches and 8 inches down from the end of the wood with the hole in, and mark them.

A dowel or pipe that is about one-inch thick and 12 inches long.Whether it’s the school holidays, or you’re just after a fun project to do at home, bungee cords are great for helping with organisation, storage, activities, and even science projects… like how to build a catapult using a bungee cord, because who doesn’t want to know this?
