We are able to arrange for a collection if that is easier for you, just get in touch and we can help with this. 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. If you choose to mod the button with a second 9V battery, have the students tape up every seam many times over.

At high speeds, tiny imperfections are quickly blown out of proportion because the forces acting upon the rocket are intensified.Most purchases from business sellers are protected by the Consumer Contract Regulations 2013 which give you the right to cancel the purchase within 14 days after the day you receive the item.

I finally added a blow off valve as well to prevent some high school kids from excessively pumping the systems up.

You can feel just like a real astronaut with this rocket toy which uses your own stomp power to give it the fuel it needs for takeoff! Tell your students about this and they will be frightened enough to never get near the tip of the launch tube. If they aren't parallel, it will be very hard to fit this Tee assembly onto the rest of the launch tube. I usually refrain from interfering with students' designs, however if a student has created a poorly built fuselage I will step in and help them. I used hose clamps to hold the holders onto the frame tubes, but zipties would probably work as well.

Since then, individuals, groups, and Maker Faires all over the world have had a blast introducing rocketry to kids and adults with this launcher.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! This side is harder to get exactly right, but since I am using it for the valve stem, it doesn't have to be perfectly parallel with the frame tubes. When we take the launchers to events, we have a lot of small 1/2 inch pipes at the tables so a lot of children can make rockets at the same time. All is needed is a person to jump with great vigour onto the air pressured launch pad and up it soars. For the groups I usually deal with (Elementary children) not having a pressure relief valve is okay because the children are always monitored while using the launchers (mainly for eye safety), and a lot of the times the kids need help from an adult to pump the bike pump anyway.

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.The student holding the button should keep his/her trigger finger off of the button until the final countdown is initiated. 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. Wrapping around clockwise makes it so that the thread tape won't unwind when screwing the pieces together. If the pressure goes over the max set on the relief valve, it will "pop" to relieve the pressure and then close again.
