Access to clean drinking water is a BIG issue, but with the invention of a tiny-but-powerful personal water purification system, South African communities could reap the benefits of a small solution.
Working in a way that's exactly opposite to that of a normal tea bag, the nano filter created by scientists at Stellenbosch University, in Cape Town, South Africa is able to suck toxic contamination right out of the water.
Small enough to fit into the neck of a water bottle, these tiny sachets are made from the same inexpensive raw materials used to produce the rooibos tea bags that are popular in South Africa.
Find out why these tea bags are also an environmentally friendly water filtration solution:http://ow.ly/2u5bx
