OT: $30K engineering challenge (but crazyjoe has an unfair advantage)

LMFAO brilliant

Shit! That is a hell of a contest. We should build a space McD's! Or if you want more privacy build a space Olice Garden

Olive Garden has all the rooms you can close yourself into. You may even get a blumpkins

The solution is easy and involves only a shaped funnel with a good seal, a hose, some hose clamps, a full flow ball valve (appropriate, no?) and a hull penetration to the outside of the spaceship. When the astronaut takes a shit or a piss, he or she simply opens the valve and everything is sucked out into the void! Potential disadvantage: the astronaut has to hope like hell that he or she can get that sucker closed before his or her innards are sucked out as well.

I offer this solution to NASA free of charge!
