When the glue dries, place an object on the bottle cap and pull back on the stick. Glue a bottle cap to the top of one of the open sticks. Use a second rubber band to secure the center of the open popsicle sticks to the center of the stacked popsicle sticks.Īdd glue where necessary to keep things stable. Wrap two ends of the popsicle sticks over the popsicle stack together with a rubber band. Take two popsicle sticks and wedge them between the stack of three sticks. Here is how to build your very own catapult made with craft sticks. Popsicle Stick Catapult Building Instructions Use these variables to see which catapult design is the best for shooting a small object across a room. Depending on how much tension is between your craft sticks and how light the object is, that will determine how far it flies. When you let go, gravity will cause it to snap back into place. To launch an object with your catapult, you hold one end of the short piece in your hand and pull down on the long piece with your other hand to bend it slightly. This action causes the catapult to launch its projectile into the air at high velocity! How far can a popsicle stick catapult shoot a small object? When the rubber band is released, it snaps back and pulls the sticks away from each other. The popsicle stick catapult works because of the elastic potential energy stored in the bent sticks. It was invented by two brothers, Arthur and Charles Paine, in 1920 as a tool for teaching their children about physics. The popsicle stick catapult is a toy that has been around for decades. How does the popsicle stick catapult work? Pom poms, marshmallows, or other small objects to fling.You will need the following items to make this catapult design: What materials do you need to make a popsicle stick catapult? A bottle cap can be glued to the craft stick catapult to hold small objects in place. The catapult is made by gluing three popsicle sticks together and then using rubber bands to connect the popsicle sticks. How to make a catapult with popsicle sticksĪ popsicle stick catapult is a type of catapult that can be made out of popsicle sticks, hot glue, bottle caps, and rubber bands. The more tension in the catapult, the farther the objects will fly. With a popsicle stick and a rubber band, the kids will build a launcher that can shoot small objects several feet across a room. Kids can become their own mechanical engineers when they create this simple DIY popsicle stick catapult project. The engineer will then turn this design into a working machine by making drawings or building models. They work in a variety of industries including automotive, aerospace, biomedical, robotics, and many more.Ī mechanical engineer typically takes a project from conception to completion by helping create a blueprint or design for the machine. Mechanical engineers use math, science, and technology to design products that move or power themselves. Mechanical engineering is the branch of engineering that deals with the design, construction, and operation of machinery. The engineering process is broken down into five steps: planning, designing, building, testing, and evaluating, which can all be applied when making a catapult popsicle stick. They don’t take long to make and it is a fun introduction to the basics of the design process and mechanical engineering, which makes this an excellent STEM activity for kids. What is a popsicle stick catapult?Ī popsicle stick catapult is a toy that you can make out of popsicle sticks and rubber bands. This is what makes it so much fun.Ĭheck out the Water Pencil in a bag and the Surface Tension Experiment too. As you dive into it more, you can see about using different objects for this science experiment as well. This activity is a great way to explore engineering and physics concepts.
