LifeStraw
Water is the most important resource on the planet. LifeStraw is an invention that helps bring safe drinking water to anybody who needs it. This is great for going camping or hiking, but it's also been a huge help for underdeveloped towns and villages that don't have easy access to clean and pure drinking water. All you have to do is stick the straw in the water and drink from it! It purifies as you go.
