Potato Cannons

  1. Dec 16, 2006 #1
    Does anyone else make potato cannons here?

    Ive made a few with hairspray and 2 pneumatic ones. The best one is over 7 feet tall. I just tested it with a reeses peanut butter cup and it shot it through a 1/4" piece of plywood. I was just wondering if anyone else has made potato cannons or anything like it.

    I've never made one myself but one of my friends made one that you used hairspray with, made lunch time at school a little more fun...haha. That thing really made those potatoes fly.

    Try MAKE magazine's podcast on iTunes. They've had a ton of videos and PDFs on how to make all kinds of them ranging from apples to pumpkins (including potatoes!).

    Im definately going to check out that podcast that sounds awesome. I was going to attempt to make a huge pneumatic potato cannon. The only problem was that my dad flipped when he saw i was shooting wood through plywood. It was so loud he thought it blew up. I have yet to hold this one i leave it clamped down in a clamp because i am unsure of the recoil. I also built a bipod when i try a potato. I have a remote firing system so i dont have to be near either.

    There was a guy here in Oregon who either killed or seriously injured his kid with a potato gun. IIRC it blew-up in his face. I couldn't find the story but I did spot this:

    I've made several. The best one was a can of LaChoy veggies, wrapped loosely in tin foil. You can blast a entire block with LaChoy mist!

    Hmm. Im suprised they said they arent safe. I read a federal law about them that says that they are safe and legal as long as they shoot potatos. Maybe ill take a little more caution now.

    A federal law stating that using a piece of plastic drainpipe and an unmetered quantity of volatile propellant to fire a hard object weighing anywhere up to a couple of kilograms a few hundred metres in a relatively uncontrolled direction is safe?!

    You 'merkins are crazier than I thought!

    We don't have a great leader.

    So where do you come up with that? I don't see Bush using this one.

    Oh yeah, I forgot about the pubic wig thing. But to me, whenever Bush is talking about his populace it sounds like he says "'merkins" rather than "Americans"...

    It's too bad that Letterman never picked up on that.

    How could you?! :surprised
    Are you feeling okay?

    Anyhow, I seriously doubt that anyone outside of PF has ever heard of a 'merkin', let alone knows the definition.
    As for the cannons, 'How Stuff Works' has a really good article about them. According to it, though, some jurisdictions have complete bans on them.

    Legal does not mean safe.

    Here in Merca, things remain legal until the appropriate lawsuit is filed. When the time comes that a serious injury results from a hairspray-fired PVC potato cannon, and a successful lawsuit against the hairspray manufacturer nearly bankrupts said company, and the hairspray lobby succesfully pushes through a ban on PVC potato cannons, it remains a lawful passtime.

    Perhaps the NRA could block it. Merca is great!

    Yep, that's why I thought it so strange that the OP asserted that he'd seen a law stating that they were safe!

    :biggrin:

    I don't think there is any such federal law. The best I could find was this: http://science.howstuffworks.com/spud-gun5.htm
