We wrapped a pepsi bottle in bubble packing and poked a whole in the side. Put a minatures bottle (w/o the bottom) in teh hole and glued it there and then filled the thing with ice. THe minature bottle is the perfect size for the hose from my hookah (it fits snugly in it) - then we smoked a bowl of skunk and mint tobacco through that - was the most refreshing hit ever just cool minty air (well, smoke). Was so good I didn't realise that I'd taken a hit first time round...
