Our B-2 Water Rocket was test flown with an unofficial word record of 7 onboard cameras in order to record video of a test of some enhancements to our free ServoChron Servo Deploy Timer Software, and our newly invented Axial Parachute Deploy Recovery Ejection System. This system was developed to fill the need for a reliable parachute recovery system that could be made from common materials which was very easy and fast to make. How To Build A Bottle Rocket And the parachute idea is good one for a smooth landing. By carefully considering these factors, it is possible to design a bottle rocket that is able to reach a high altitude, fly straight, and return to the ground safely. Now drill the hole in the tennis ball using a drill.The hole is where you will pass the shroud lines through and make a knot so they will not come out. Be cautious once you start pumping and do not approach the rocket, even if it appears that nothing is happening with the launch, as this can lead to injury. In simple terms, the lighter your bottle rocket is, the higher it will fly when its launched. *Save the neck you will use it in the next step.*. Assemble and decorate your rocket, using the pencils as 'feet'. Repeat for all the bottles you have.Pick the best bottle for the engine.This means make sure there are no holes or cuts in the bottle.You should never have to cut the engine bottle. Instead, the sections would tumble slowly down, reducing the chance for injury or property damage on the ground due to a "lawn dart".

U.S. Water Rockets has just announced a newly created photo documentary journaling their Experimental Water Rocket Launches in the form of a Microsoft Windows Compatible Screensaver for all PCs. If your students are anything like mine, they will bring some suppliesbut not all of them. He had to heat the bottom of the bottle so it would get a rounder shape. On September 2, 2004 U.S. Water Rockets set a new single stage water rocket altitude record with an average altitude of 1,421 feet, beating the old record of 1,242 feet that was held by Anti-Gravity Research. The physics behind the bottle rocket is Newtons 3rd Law that "For every action there is an equal reaction." You will need the following: You can also paint the plastic bottle if youd like to decorate it further. "I needed a little help with a school project and this gave me a brilliant idea on the project so it helped a lot. For the top bottle, when you cut the opening off, do you need to tape it? This prompted U.S. Water Rockets to take a "clean slate" approach to the problem. A successful bottle rocket design is one that is able to reach a high altitude, fly straight, and return to the ground safely. Historically, ease of assembly and reliability have been mutually exclusive goals. Note: this manual includes the ServoChron assembly, programming and operating manuals into one convenient file. Step 2: Drill Into Cork. Place the fins on the lower part of the cut bottle. This tutorial will show you have to construct a very reliable and lightweight acceleration switch which you can use to activate electronic systems on your rocket such as a ServoChron Single/Dual Servo Actuated Parachute Recovery System. 11 years ago -Fins made of your cardboard Subscribe: http://bit.ly/2tbQbmiIf you love this channel and want to help us out, a like, subscribe and/or share would mean a ton.Watch more JoshBuilds: https://www.youtube.com/playlist?list=PL4oi-j0WQbOvRMsTw_YSVtWkfsA0lGq0U Follow JoshBuilds:Facebook: https://www.facebook.com/joshbuildz/Twitter: https://twitter.com/joshbuildzInstagram: https://www.instagram.com/joshbuildz/Parts:At your local hardware store obtain:36\" long of 1/2\" PVC pipe2 - 1/2\" Tee peice1 - 1/2\" cross peice4 - 1/2\" 45-deg elbow peice5 - 1/2\" cap peice1 - valve stem cut from bike inner tube1 - wine cork2 - 2L pop bottlesWatch More JoshBuilds:big builds https://www.youtube.com/playlist?list=PL4oi-j0WQbOsOnmohmra2_r6El_u6-ly0best diy projects https://www.youtube.com/playlist?list=PL4oi-j0WQbOttaVQaEG-wvbuvSqOEGuT4mini vehicles diy https://www.youtube.com/playlist?list=PL4oi-j0WQbOuX9jagZ1ZYync7p8oJUNrprecent uploads: https://www.youtube.com/playlist?list=PL4oi-j0WQbOu-1BW0P9IZ29xbSjWeagZ6 Many teams build their rockets in this manner using a pre-manufactured commercial product used in school science experiments commonly called a "Tornado Tube" or a "Vortex Bottle Connector".
