EXPERIMENTS IN WATER ROCKETRYDISCLAIMER: The hobby of building and launching water rockets can be dangerous. No one should attempt to do so with out adult supervision and the knowledge of the hobby. Rockets are highly pressurized and the same precaution that is exercised around high pressure equipment also applies here.This webpage is just my documentation on my building and launching of water rockets. If you do a search on the internet for "water rockets" you will find all kinds of documentation. I took a lot of that and combined it into my project. For those that don't know what the heck all this is, it's simple. Take an object and put some water in it and then pressurize it. Now, let it go. The rest is Newtonian physics. Determining AltitudeI use a home made tool to measure the angle a viewer at a certain distance sights the rocket at its apex. Using a little trig with the known distance of the viewer and the angle they measure, you can determine the approximate altitude. Picture of it here.back |
