Would sex even be possible? Surely you'd only manage one thrust before your partner is propelled across the room.
I'd try and make a ball of each element, and find some way to make them orbit me. I am the master of all!
In reality, I'd probably just get motion sickness and throw up. Although watching everyone else frantically flailing their arms in vain in an effort to propel themselves away from the vomit balls would be hilarious
EDIT: Oooh! Id also completely re arrange any of the other crewmans rooms when they were out, so they'd forget where the ceiling was
