LifeStraw
Millions of lives have been saved by these amazing inventions. They solve problems that were costing lives in ingenious but often simple ways that you'll probably wish you had thought of!
The LifeStraw is a cheap, easily portable water filter system that was designed for people in developing nations without access to safe, clean drinking water to use. It purifies water instantly as water is drawn through it, filtering out 99% of impurities, such as bacteria, viruses and parasites and one straw filters 700 liters of water, which is enough drinking water for one person for an entire year.
