Science at work - The LifeStraw. The LifeStraw removes at least of 99.99999% of waterborne bacteria and can filter up to 1000L of water. Throughout the world, an estimated 884 million people still do not have access to clean sources of water. According to the LifeStraw manufacturers, the device contains no chemicals or batteries and makes it possible to drink safely from any river, lake or puddle.
