A simple invention, a bottle of water and a couple teaspoons of bleach

I’ve found a news for an invention for BOP in the Philippines.

MIT innovated “bottle light” filled with small amount of chlorine.

Actually, I have not known that many poor people in the Philippines are living in dark and small houses. It was very difficult to imagine people in sun-bright countries live in such a place.

Thus, I am amazing that MIT students knew such on-site demands. Also, it is very important to visit where demands exist.
