  Homemade Air Cannon (Shoots Over 100′)

Posted: September 8th, 2009 View Comments

   WARNING: This Device is HIGHLY DANGEROUS – Use this Info at your OWN RISK!

I will start out by saying that the potential for serious injury, even death, is possible should this device rupture or explode while under pressure! While certainly safer than similar devices using flammable liquids to create launch pressure, great care must be taken to assure all glue joints are properly prepared and have had time to completely cure before attempting to use the cannon… Even then it is possible for the device to fail at any time and I accept no responsibility for damage, injury or death caused by the use of this device.

With that said, the components needed to construct the Air Cannon include:

  • one 5′ section of 3″ PVC pipe
  • one 3″ PVC cap
  • two PVC adapters (mine adapt from 3″ to 1″)
  • two 1″ PVC to 3/4″ threaded adapters
  • one can PVC cleaner/primer
  • one can PVC glue
  • three 3/4″ close nipples
  • one 3/4″ ‘ball valve’ (used to ‘launch’ the cannon)
  • one 3/4″ x 3/4″ x 1/2″ tee
  • one 1/2″ x 1/4″ bushing
  • one 1/4″ thread ‘bicycle valve’ (used to fill the tank with air)
  • You will also need a saw (or something to cut the PVC pipe), some thread tape or ‘pipe dope’ and something to fill it with air (a small portable compressor with a pressure gauge would be my choice). Additionally, we use the bottom of a plastic tennis ball container to act both as a guide and seal. It fits almost perfectly into the PVC pipe and when inserted open end first (or down) it is a nice platform for the object being launched to sit on. We have also found getting the inside of the ‘barrel’ wet helps to avoid things binding up as they are launched (if you do not wet the inside of the barrel water balloons will normally burst instead of being launched).

    ABOVE:
    Detail on the two valves needed, obviously the fill valve (or bicycle valve) must be positioned between the tank and the launch valve.

    BELOW:
    Tank Detail, showing how the components fit together…

    The pictures give a good visual on how this thing is put together, but here is some other helpful information. We cut 18″ off of the PVC pipe to use as the tank, using the PVC cap on one end and the reduction adapter then the threaded adapter on the other. The remaining piece of pipe received the reduction adapter and threaded adapter on one end and nothing on the other. Everything was cleaned with PVC primer and then carefully glued together, being allowed to dry overnight. We then assembled the valve section using the pipe fittings as shown above and threaded the tank section and barrel section onto it.

    To increase the safety of this device, it would be possible to construct the entire tank section from steel pipe fittings. 3″ or 4″ steel fittings and adapters down to 3/4″ could be used in place of the PVC tank and would eliminate the potential for the glue joints or PVC pipe itself to fail under pressure.

    I recommend wearing safety glasses and testing at low pressure (say 10psi), then slowly increasing that figure to a MAXIMUM of from 60 to 80psi (ours holds at 80psi, yours might explode in your face for all I know, I am NOT suggesting these are safe pressures).

    Anyway, this cannon, when using the ‘tennis ball container’ seal and a launch angle of about 60 degrees, is capable of launching a full 20oz plastic soda bottle well over 100′ up into the air. Needless to say it has some serious punch and if the object being launched was to hit a person the results would assuredly be undesirable, so PLEASE use caution and common sense should you decide to build and use the device.

      Wax / Water Fireball…

    Posted: August 11th, 2009 View Comments

       WARNING: This Procedure is HIGHLY DANGEROUS – Use this Info at your OWN RISK!

    We have done this a few times when on camping trips and it is fairly impressive, even creating a ‘mushroom cloud’. Of course the potential for SERIOUS INJURY or DEATH exists… Not to mention the risk of extensive property damage taking place if things go wrong. I do not recommend that you try this and will accept no responsibility if you do and end up burning down half the planet! DO NOT ATTEMPT THIS INSIDE OR NEAR ANY STRUCTURE!

    What is Needed:
    Fire/Heat: A campfire is likely best, you need to be able to boil wax…
    Wax: From candles or wherever.
    Metal Can: To put the wax in…
    Cup of Warm/Hot Water: I suggest you attach this to the end of a 10′ pole…

    How it is Done:
    The smart individual would never attempt such a dangerous thing as this, but if you are going to do it anyway… Please, start small, maybe 2 ounces of wax in a soup can…

    Put your wax in the metal can, the can should only be about 1/3 full of liquid wax for best results (and safety). You must now place the can on your fire, a cooking tripod works best. Be aware that if your can is not stable you are asking to be severely burned or killed.

    Once the wax begins to boil (it may also start on fire) you are ready. Fill the cup (that you have securely attached to the end of a 10′ pole) with about the same amount of water as you have wax in the can, maybe just a bit more. This is by far the most dangerous part! CAREFULLY but swiftly dump the water into the can of wax, the effect will be IMMEDIATE, you will NOT have time to move away from the fire, so protect yourself!


    Awesome fireball huh… Obviously, the more wax you have the bigger your fireball will be… I am sure there is a limit, even if simply for safety’s sake… Don’t be stupid and end up killing yourself by trying to use 30 gallons of wax! A large coffee can filled with about 8 ounces of wax will easily produce a 25′ (or bigger) fireball and the heat produced comes close to spontaneously igniting the shit you will dump in your pants when it happens.

      Sun Jar Solar Light

    Posted: August 6th, 2009 View Comments

    I thought this would be kind of nifty for camping trips…

      All or Part of this Post was Imported... Original Source Credit is at the end of the Post.

    The Sun Jar is made with a traditional Mason jar and high tech energy efficient lighting. Captured inside the jar are a highly efficient solar cell, rechargeable battery, and low energy LED lamps. When the jar is placed in sunlight, the solar cell creates an electrical current that charges the battery over a few hours. This energy is then used at night to power the three LED lamps inside the jar. The light is diffused by the frosted jar and available in yellow or blue (Moon Jar). There are no visible controls on the jar, the result of a clever light sensor inside that automatically activates the lights when it gets dark or lights are turned out, though there is an override switch inside the lid to turn off the light at night and conserve battery life. The Sun Jars are completely water tight so they can be left outside in any weather conditions.

    Sun Jar $40.00 from Uncommon Goods
