Absolutely love this simple idea; a used plastic bottle is filled with bleach to magnify the power of the sun and lights up impoverished communities. The Liter of Light (LOL) started as a small local initiative in the Philippines and has since been adopted by Pepsi around the world fundraising for the initiative.
Impact:
By 2015 LoL raised 1M$ from consumers all over the world and more than 190,000 day lights have been installed.
