How to Create Solar Light Bulbs With Nothing But a Bottle and Some Bleach

Millions of homes use Kerosene for lighting, even in 2015:

"Families not connected to grid electricity in Africa spend some USD 10 billion every year on kerosene to light up their homes."

I have some concerns about the bleach. I think we should be using Iodine, Citric Acid or something else to keep the water pure, but the basic idea is there:

“It’s a divine light. God gave the sun to everyone, and light is for everyone. Whoever wants it saves money. You can’t get an electric shock from it, and it doesn’t cost a penny.” Alfredo said.
