![]() ![]() Glue the lid on the end of your catapult and place your puffball there to launch. Instead of using a spoon, you can also take a bottle cap from an orange juice or a milk jug. In fact, it is a valuable learning experience for your children to see you adapt and improvise. It is okay if your STEM project doesn’t look perfect. How do I know this? Because I’ve had to do it. No plastic spoons around? No problem, you can use a spork and it works just fine. Seriously, a simple popsicle stick catapult design can be made with so many household items. I’ll give some alternatives to them further down.ĭIY popsicle stick catapults are a great STEM activity because you can make them with so many different items. If you don’t have any of these items, don’t worry. Puff Balls, Mini Marshmallows, Pom Poms, or Small Plastic Ball.If you do crafts regularly you probably already have them in your supplies! You only need a few items to make these awesome DIY catapults. So here are the full directions and explanations for year-round fun! (Scroll to the bottom for free printable instructions!) Craft Stick Catapult Supplies And this is too much fun to leave for just the holidays. (You can see it with other fun holiday activities: 5 Minute Christmas STEM Activities.) It is perfect for shooting ‘snowballs’ all winter long.īut a lot of people have told me how much they like it and wanted more information. We originally did this activity a few years ago as a snowball shooter. Popsicle Stick Catapult Printable Directions.How To Make Your Popsicle Stick Catapult. ![]() Under Siege! Use a Catapult to Storm Castle Walls: explore the settings on the Ping Pong Catapult that control whether the ball will fly into into a castle wall or over it.Two-Stage Balloon Rocket: build a multi-stage balloon rocket and explore Newton's laws of motion.Build a Popsicle Stick Catapult: build and experiment with a simple catapult made from wooden sticks and rubber bands to explore the physics at work in a catapult.Paper Rocket Aerodynamics: explore the design of a straw-blown paper rocket and the variables that affect its flight.Mini Trebuchet: make a mini trebuchet from wooden sticks and craft materials and see how the movement of the lever arm relates to the path and distance of the projectile.Launching Homemade Baking Soda Rockets: learn more about chemical reactions when you blast a homemade rocket into the air using baking soda and vinegar.How is this different than a chemical reaction? Erupting Diet Coke® with Mentos®: explore the physical reaction that happens when you mix Diet Coke and Mentos.Build a Gauss Rifle: use magnets and ball bearings to set up a Gauss rifle and experiment to see how the number of magnet stages relates to the flight distance and velocity of the ball bearings.Bottle Rocket Blast Off!: investigate how the air pressure you create in a bottle rocket before launching changes the maximum height it reaches once launched.Bombs Away! A Ping Pong Catapult: experiment with the Ping Pong Catapult to find the right settings to launch a ball into a target.What catapult settings produce the most consistent results? Bet You Can't Hit Me! The Science of Catapult Statistics: gather data about how far balls travel when launched from a catapult, and then use the data to construct a histogram.The following Science Buddies projects explore the science of launching and catapulting with trebuchets, rockets, catapults, or similar devices and setups:
