![]() ![]() You probably heard of Newton’s Three Laws of Motion ( source): The biggest benefit of STEM projects is that you can show your kids the science visually, which helps them understand the concepts. The Science Behind the Popsicle Stick Catapult If you are looking to do this activity with a group of students in a classroom, then the first catapult design with rubber bands is probably the way to go. The downside is that you need to use hot glue, so preschoolers or kindergarteners, or even elementary school kids can’t build the popsicle stick catapult independently. With just a little pressure on the bottle cap, you are able to really launch the projectile far. This popsicle stick catapult design is simple yet effective. Hot glue the bottle cap to the other end of the popsicle stick. Again, I applied extra glue to the metal part of the binder clip.ĥ. Glue a popsicle stick to the top of the binder clip. I used extra glue around the metal part of the binder clip to make sure it will stay attached to the popsicle stick.Ĥ. Glue the binder clip to the end of the top popsicle stick. Glue one popsicle stick to one of the points of the triangle and glue the other end to where it bisects the opposing side.ģ. Form a triangle with 3 popsicle sticks and glue the ends together.Ģ. Design 3: Catapult with Popsicle Sticks, Binder Clip, and Bottle Cap Materials:ġ. The catapult with the bottle cap seemed to shoot higher, but the horizontal distance of the projectile was shorter. However, since the spoon extended the arm of the catapult, the catapult with the spoon could shoot farther. I also like it because you can put different objects in the cap and not risk having them fall out since the cap is deeper than the spoon. With the bottle cap, the catapult felt more stable. Simply hot glue the bottle cap to the end of the popsicle stick where the spoon was from the other design. To do this, you need a hot glue gun and a cap from a water bottle or sports drink bottle. This popsicle stick catapult design is very similar to the one above, except you are replacing the spoon with the bottle cap. Release the spoon and watch the ball fly! Design 2: Catapult with Popsicle Sticks, Rubber Bands, and Bottle Cap Hold the catapult with one hand, use the other hand to push down the spoon.ħ. Use two rubber bands, secure the plastic soon to the upper popsicle stick.Ħ. Pull the 2 popsicle sticks apart and wedge the stack of 7 popsicle sticks between them.Ĥ. Make a stack of 2 popsicle sticks and use a rubber band to tie them together on one end only.ģ. Make a stack of 7 popsicle sticks and use rubber bands to tie them together on both ends.Ģ. Styrofoam Balls (or Pom Poms or marshmallows or anything that fits in the spoon)ġ.Design 1: Catapult with Popsicle Sticks, Rubber Bands, and Spoon Materials: Here are 3 simple DIY popsicle stick catapult designs that you can build with your kids with materials you have around the house. Then I started experimenting with different ways to build the popsicle stick catapult to make it shoot farther and more powerful. How fun! I went home and built it right away. One day, I saw in a magazine instructions on how to make a catapult with popsicle sticks, rubber bands, and a spoon. It’s a fun STEM project that you can do with your kids indoors on a rainy day!ĭo you have popsicle sticks or craft sticks somewhere in the house? If you are a parent of a toddler or preschooler, I bet you do. Here are 3 tried and true catapult designs that are easy to build and test. Only put the quarter stick half on the full sticks when gluing.Check out how you can make a simple popsicle stick catapult with materials you probably already have at home. Glue together 4 full and 2 quarter sticks together "log cabin" style with long sticks on bottom. Glue together 4 full and 2 half sticks "log cabin" style with long sticks on bottom 6 Quarter Popsicle sticks (1 stick cut in quarters and the 2 quarters left from the ¾ sticks).2 Popsicle sticks cut in half (4 Half Sticks).This is a great little ballista project that was submitted by a web visitor (Jesse L.) You can see more on his youtube channel here: Drako155Video where you can watch the build of this ballista. My name is Will and if you have questionsĬontribute projects or ideas you can contact me
