Once you’re done, remove the plug from the bottle. Alternatively, line your existing plug with duct tape to make it larger. If it isn’t a snug fit, find another material to use as a plug.
It will let you see how your rocket design is progressing and make changes before you get too far along. Now, decide how you want to close the top. You want the rocket to be as close in diameter to the pipe as possible so all the air goes towards launching the rocket rather than leaking out. To make the body of the rocket, use the launcher to roll a piece of paper around (or use your spare PVC piece if you have one). If possible, tape the launcher to the base.Ī launcher is no fun without a rocket! There are lots of engineering and design choices to make: Short body or long? Fins, wings, or neither? A nose cone or a flat nose? What kind of paper? Each decision will impact how your rocket flies. You have a launcher! The last step for the launcher is to find a base to put under the first tube to hold the launcher steady.
Connect the second piece of PVC to the elbow and tape them securely. You’ll need to replace the bottle eventually and will thank yourself when you can separate it without too much hassle.Ĭonnect an elbow piece to the end of the PVC pipe and tape them securely.Ĭonnect the second elbow to the first, but don’t tape them together! This is how you’ll adjust the launch angle. Any time you use tape, the point is to make as close to an air-tight seal as possible, but here, you will want to use only as much tape as gets the job done. Insert the first inch of a piece of PVC pipe into the 2 liter bottle and tape them together. If your PVC pipe is smaller than the bottle opening or the elbows, wrap tape around it until it fits snugly. (Optional) paper clips or other “payload” objects.(Optional) An extra piece of ½” PVC pipe.(Optional) Markers, stickers, or other means of decoration.This will be something you find at home (a book, box, brick, etc) 2 liter bottles (multiple- they will break over time!).
You may even be able to order online! Launcher Image Caption: Supplies needed for a do-it-yourself stomp rocket launcher You may already have these supplies at home, but if not, any hardware store will have the launcher pieces. There’s a kit you can buy that sends you everything already pre-made, and that’s good and quick…but where’s the fun in that? Build your own stellar do-it-yourself stomp rocket and launcher and blastoff into the cosmos with your family. As the Manager of Program Development, I include them in Adler’s camp activity list every year and they make frequent appearances at home with my daughter too. When I’m looking to combine a little bit of learning with a lot of fun, stomp rockets are my go-to.
