Always check with a parent or guardian before you start a project and make sure it is okay to use materials you find around the house. We developed cannons and missiles, which have much greater range and accuracy and required less manpower to fire. The idea of using the sudden release of stored to launch something, however, is still useful. The counterweight would be attached to one end of a beam that pivoted on the machine's frame.

Perfect for an engaging hands-on activity, this guide provides clear, step-by-step instructions to make a mini-engineering marvel that can launch lightweight objects with ease. As they measure distances and observe how different variables affect the launch, children learn through hands-on experience. Get ready for an entertaining session of building and discovery that can inspire a love for science and creativity in your young learners. Crafting a popsicle stick catapult can be a fun and engaging project for all. This guide offers 20 easy popsicle stick catapult designs that show you precisely how to make one from scratch.
The Coolest Preschool Science Activity - Surface Tension
The conservation of energy is a fundamental principle in physics that states that energy cannot be created or destroyed, only changed from one form to another. In the case of a catapult, as the device releases the potential energy stored in the flexible material is converted into kinetic energy as the projectile is launched. This Lego catapult uses tension from a rubber band to launch the projectile. The rubber band is attached to the front end of the throwing arm and to the back of the base. By pushing down the throwing arm, the rubber band is stretched and energy is stored in it. When the throwing arm is released, the rubber band contracts and propels the projectile forward.
Step 13: Test It Out!
A few feet in from the back of the catapult, on the upward sloping braces, drill a hole through each brace, so that a metal pipe can fit though the holes. Cut and place a metal pipe into the holes, and leave a bit sticking out on each end - this will be the spool. Weld another pipe onto the spool, as to create a means to wind the spool with some sort of crude metal handle. Tie one end of the nylon rope around the spool and the other end around the S-hook. If you use the carriage bolt, you'll have to grind it down so that it's smooth.
The other end of the beam would be attached to a sling that would contain the payload. When fired, the trebuchet's counterweight would be released. As the weight falls, the opposite end beam springs upward, pulling the sling with the payload in an arc over the machine. In the medieval world, warfare often involved beseiging, or surrounding and attacking, a fortified location like a city or castle.
Engineers are exploring novel ways to harness energy, precision, and automation to push the boundaries of catapult technology. Fast forward to the Roman Empire, where the ingeniously engineered “onager” catapult stole the limelight. Imagine a wild, kicking donkey (yes, that’s what “onager” means), but one that could launch stones with devastating force. These early catapult designs laid the foundation for the magnificent machines we know today.

Hope you will enjoy this wonderful DIY project that inspires a lot of investigation opportunities. It is also important to have a designated launch area and to follow proper launching procedures. Since then we have adapted catapults to have fun and launch various objects, but did you know that there is an actual science behind how far an object would go? It’s true the heavier the object or the further back you pull the catapult will determine the trajectory of each object.
They also explore geometric principles when determining the launch angle and trajectory of the projectile. For this project, we used our engineering skills to actually build the popsicle stick catapults. We used science to test how far the catapults flung the items we chose. A classic and awesome simple activity that is appropriate for the kids of all ages and especially the older kids learn the math and physics using simple household supplies. Turn your little scientists into little engineers to understand simple catapult machines.
Step 3: Step 3 : Making the Tower
Gather two larger craft sticks or tongue depressors, eight smaller popsicle sticks, and some small objects to launch. Engage in a fun and educational STEM project with your child by constructing a popsicle stick catapult as outlined by Parenting Place. Ideal for kids aged 5-12, this activity encourages connection, problem-solving, and honing math skills. Gather some simple supplies like popsicle sticks, rubber bands, and a wooden spoon, and start by decorating your spoon.
Be carful indoors with this one – it can launch objects quite a distance. As the title suggests, this so simple activity of making simple catapults using only three ingredients and simple instructions. If your children are new to catapults, then this would be the perfect activity to introduce your younger kids to the catapult physics in a simple way. Initially, it starts out as a craft activity but ends with a ton of fun while making this simple catapult.
Avoid using hard or heavy objects to prevent injury or damage. After launching the projectiles, kids can measure and record the launch distances at different angles or with different weights. Analyzing the data allows them to draw conclusions about how changes in the design or launch parameters affect performance. Once you’ve mastered the basics, why not take your catapult-building skills to the next level?
Learn how to make a DIY popsicle stick catapult with the help of crafts by courtney! This project is perfect for young minds eager to explore the principles of stem, including engineering, mathematics, and science concepts like gravity and force. Simple materials like jumbo wood craft sticks, rubber bands, and bottle caps are all you need to get started. Step-by-step instructions make assembly straightforward, and the project is suitable for a wide age range, making it perfect for family activities or educational settings. Experiment with different projectiles and angles to explore the concepts of potential and kinetic energy in a hands-on manner. Gather your popsicle sticks, rubber bands, and a plastic spoon, and get ready to launch into a memorable learning experience.
For this we use the top of a pizza box, though you can just use a piece of paper if you like. We used a small “L” shaped angle piece to hold the projectile. They have been proven to be one of the most effective mechanisms during warfare. That is pretty amazing, given that making a catapult is relatively easy. Here are a few resources that will help you introduce STEM more effectively to your kiddos or students and feel confident yourself when presenting materials.
This design uses the arm to stretch the rubber band, which will then exert a force on the throwing arm, launching the projectile. This design allows for a stable and consistent launch and can be adjusted by changing the length of the arm, or applying more or less pressure. During the build, we found that when we launched, there was enough force that the throwing arm flew right off the catapult. We had to add some addition plates and pieces to secure it. Use the pieces you have available to make your design sturdier or more effective. This is where critical thinking and problem solving skills get a bit of a workout.
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. You don’t need tools to construct it, just some popsicle sticks, rubber bands, and a little creativity. If you want to make it fancy, you can add a bottle cap to act as a basket for your projectile.
At Design CATAPULT, we have all the resources required to take your design from concept all the way to production. We welcome you to explore a vast collection of engaging and easily accessible crafts at DIYCraftsy. It pairs well with this written guide, adding a dynamic visual perspective to the crafting process and making the instructions even clearer. Create a target with different numbers in different areas and use the lolly stick catapult to fire balls at the target.
