Kibera, Nairobi - On Nov 22nd 2012: A group of the Adventure pride Centre pupils demonstrate the process of making the water bottle bulb. One of these "do-it-yourself" lights takes maybe an hour to install. Cutting an appropriate hole, inserting a bleached-water-filled bottle, and resealing around the resulting gap. Even where clean water is rare, a little can generally be spared for almost a decade of lighting. In addition, bleach is added to the water to avoid contamination of the water thus making it last and shine longer.
