![]() ![]() ![]() The man said he had been doing it for years and never had a problem. The amount of ether was very small and very effective. WORKED! Really worked! Those potatoes went so far that I never saw a one reach apogee! The kick was amazing! I had a ball and if it hadn't been so far from civilization I'd have gone to the store and bought another 25 lbs of potatoes! I found out that day that is one of the funnest things a guy can have! A broomstick, a ten-pound sack of potatoes, the PVC barrel and PVC chamber and piezo ignitor and a can of. I had heard the phrase once before but had no idea what it was. Closing the gap and coming to a stop resulted in my introduction to a potato gun. I'm in my Jeep (now we're back on topic)(94 YJ, so it's shortwheelbase!) and heading south when I perceived some three individuals holding a long tubular thing and moving it around and causing some thing to happen at some distance. You know, OFFROAD! A little map recon and off I went to find the American Canal because there is a dirt road beside it and it looked like I'd be able to cover some distance in a small amount of time using it. Ten thousand people in one place and ALL vehicles are OFFROAD! That is just at Comp Hill! At night! Anyway - on Saturday I decided to see if I could go to Mexico without officiallly crossing the border. Now to an Okie this is the biggest party I've ever seen. OK let me get this back on topic, real quick like!Ī couple of years ago I went to Glamis for Thanksgiving weekend. You get money for more collage, a paycheck twice a month, you get to travel, and best of all, YOU GET TO BLOW SH*T UP!!!! KID, get your education, and a little collage, and join the military, they are looking for people like you!! This is a good way to teach physics and chemistry! When was the last time you saw a kid actually WANT to learn chemistry? I blew one to hell and back, and I would have never thought that there was enough to make it even go off. Straight butane works pretty good too, but you can get into trouble real quick with it.ĭesign of the combustion chamber is crucial to REALLY long range, and the approach angles to the barrel from the combustion chamber.ĭon't get the bright idea of using acetylene from a cutting torch or carbide chips, that will be a HIGH order detonation, and you may be picking pieces of you potato gun out of your forehead. That cheap Suave or how ever you spell it. It would be awesome, but I don't thinnk I want to pay hospital bills that big. ![]() Keep in mind I am using schedule 40 PVC, so no oxidized reactions or Hydrogen will be used. The spark is pretty dang big, and lights off every time. Because it takes such a small force to push a wet potato down an equally wet PVC barrel, an extremely powerful explosion isn't a must.įor the ignitor, I am using an Bar-B-Q grill ignitor. From my research, it is not as much the size of the explosion, but rather the speed of the explosion. I need a reaction that has most of its force exerted very early in the burning process. So far I have gotten the best results from Right Guard (a mixture of propane, butane, isobutane, and all that wonderful powder and perfume). My actual question is, what is the best fuel to use in the combustion chamber. So I have decided on the Potato gun as my project, but have yet to get my teacher to approve it. What in the world could be more benificial than making a potato go really really really far away really fast? So I got to thinking about the most benificial reaction possible. ![]() The assignment is to come up with an experiment that illustrates the benificial chemical reactions all around us everyday. Now that school is back in seesion, and along with that great portion of my time comes chemistry, I have to come up with a suitable project. ![]()
