When life gives you lemons:

  1. Take a length of PVC pipe, about three feet long.
  2. Find a high powered air compresser
  3. Devise a loading mechanism. I reccomend muzzle loading, mortar style
  4. Devise a trigger mechanism. Many air compressers allow air to be stored in a canister to be released later, these work best when modified for large volumes of air.
  5. Finally, go hunt down the bastards that gave you these crappy lemons.
Note: I don't condone unlicensed lemon-guns.
