This plastic water bottle is fitted with a NASA inspired filtration system so powerful manufactures claim it can turn cola into clear, colourless drinking water.
ÖKO's 'advanced filtration water bottle' draws on technology originally developed by NASA to ensure the drinker's every sip is 'pure, fresh and clean'. This video footage of the bottle being put to the test shows it being filled with brown Coca Cola which, after being poured through the special filter cap, looks exactly like water.  But I guess we would have to taste it to see how well it really works.  This would be perfect for a zombie apocalypse if there were only cans of soda pop left in vending machines.
