I made a very detailed video on how to build a launcher, but since it is such a long video, I made this tutorial as well since seeing the steps one at a time is sometimes easier. Grab a bicycle pump and this kit and send homemade paper rockets soaring hundreds of feet in the air!

Since this first introduction, Rick and Keith have continued to innovate in several areas in compressed air rocketry, working to make compressed air rocketry an accessible and safe introduction for kids of all ages to make all kinds of things that fly. Use a bright rope to define a safety zone that the students may never cross, even while loading their rocket. Don't forget to sand about an inch on one side of the launch tube, and then sand the inside of the 3/4 inch to 1/2 inch connector. Fins that are not attached straight, or the leading tip of the fin is not secured, will cause the rocket to tumble at high speeds.

For example, a nosecone that leans slightly to one side may not significantly influence the rocket's performance at 40psi, however at 60psi that nosecone may create an imbalance of friction created by the air rushing by, causing the rocket to turn sharply and tumble to the ground. With our wide range of tents and accessories, you can embrace the cold, crisp winter air as you explore frozen landscapes and winter wonderlands. Keep that in mind when purchasing the parts, but all of the instructions still apply even if you change the sizes a little bit.

It also keeps the valve stem and relief valve more inline with the design instead of hanging off of an elbow and tee connector. I mounted the launch buttons in a box inside the frame for easier carrying and to have all the pieces inside. You'll be able to track the parcels journey back to us, so we can process your refund in the quickest possible time. Also featuring several stickers of NASA imagery for you to decorate around your bedroom or wherever else you choose! The parts are easy to find and the pressure rating far exceeds what the kids can pump the systems to.

No need to tighten it all the way because you will use the sprinkler valve to tighten it the rest of the way.

In fact, this launcher has been used at Maker Faires in both the Bay Area and New York City to launch thousands of rockets over the course of the weekends. Featuring a launch pad and platform, once assembled, simply stomp on the foot pump to launch your rocket and watch it soar just like the real thing! Quickly insert the connector into the Tee, twisting a quarter turn while pushing the pieces together.The launch tubes length doesn't matter much, but I made it this size to prevent it from being longer than the total length of the air chamber. You don't need to use the launch tube to line things up since the other side should be even with the launch tube, then assuming your table is flat, the newly glued side should be parallel with the first side. Since the launch tube essentially multiplies the angle at the T and elbow joint, you should be able to get them lined up closely.

The box says for six years and over, so if you have kids younger than this as we do, please ensure you are the one operating it, or hands-on supervising. From cozy birdhouses to nourishing feeds and feeders, find everything you need to keep your backyard birds happy and healthy this season. Glue one of the elbows to the Tee and while pushing the pieces firmly together, and make the launch tube parallel with the 13 inch tube. I highly recommend close supervision to prevent users from over-pressurizing the system, or to add a safety relief valve. After building many versions of this launcher, I've found the best cost vs performance vs transportability vs safety size of pipe is 1 1/2 inch PVC pipe and fittings.The kids usually really like picking out the different colors of paper, and drawing on their own designs. If you're doing an event for a bunch of people, then having some nose cone and fin templates printed out ahead of time really helps out. Also includes several fantastic stickers with NASA imagery for you to use and give a space theme to whatever you choose. If using an electric miter saw, we found it best to put the PVC in place, start the saw off of the PVC, bring the saw down through the pipe, and then leave the saw down until the blade has stopped. Say goodbye to the unpredictable weather and hello to a cosy and efficient way to keep your clothes in top condition.
