The Ultimate Beer Bong

Not many Beer Bongs have their own domain, and usually for good reason, but this multi-stage, multi-person, compressed air powered Beer Bong truely deserves it's name: The Ultimate Beer Bong.
"My good friend, Billy Holder, and I created what we called 'The Device' some time ago. It was a successful over complication of a beer delivery funnel, also known as a 'beer bong'. Sadly Billy moved out, and there was a deep loss felt from 'The Device' and such the incarnation of 'The Device 2.0¨'. This was to be the biggest, most over complicated, most over engineered beer bong ever created. In fact it was to be such a spectacle it was to have it's own documentry website, and thus you have read this, and it has been done.
The basic idea, simultaneously tap two beer sources being either a sankey Keg, or a 5-gallon party ball, push it with a replenishing air compressor to either a faucet, or up to a 4-gallon upper holding tank with four hoses leading off into four mouths racing to finish their hose.
Specs:
Media type: Keg / Partyball / Water / Air
PSI: Tank-120/First drop-30/BeerSwitch drop-12-14
Upper Tank: 4-gallon capacity with hoses / Activly intercooled via radiator and refidgerator based resevoir.
BeerSwitch: Able to redirect water, air, or beer from two sources into two faucets, up to the main tank, or all three at the same time. "
