INSTANT WATER - JUST ADD WATER

A Danish inventor hopes to put a dent in the world’s drinkable water shortage with a cool new drinking straw which purifies the water as you drink. Torben Vestergaard Frandsen has created the LifeStraw, a flute-sized device which has several built in filters to remove bacteria and parasites from the water as it is sucked through. Frandsen hopes his invention will help solve the problem of water-borne diseases which kills about 6,000 people every day in developing countries. (BBC)
