I uploaded several AVI (quicktime movie) files of the infamous beer cannon and such from the armour-in a couple weekends back I hosted. Nothing historical about the cannon! It's a 12" barrel, 2.5" bore which shoots a Coors Light can filled with sand about a 1/4mile. They will work with newer microsoft viewer and other video players as well.

There a ton of people trying to view these, so it's probably easier to download, then view as opposed to trying to use mediaplayers via direct link. Either way they are big files so you need a fast connection!
