LMAO ^^ Even more if you think cubic feet :rasta: but I think it would end up being a waste. If you REALLY want to get crazy fill a mother fuckin air mattress! then have hookah pipes attached :jawdropper:

Me and my friends did something similar we put a huge bowl at the in going side of the mattress pump that fit perfectly then just packed it and turned the pump on filled the mattress and had some pipes to inhale ready to go. Put something heavy on the bed (after its inflated) if you really want some fun.
