In order to integrate the found out parameters i started cutting bottles to generate more shapes in which water and a level holding candle could be integrated in a simple way that could be reproduced by Stacy and Kevin as well.
It turned out the simple way could not be found. More and more problems showed up that i could only find complicated solutions for.
Light Bulb Reuse
We found out that round shaped glas filled with water focuses the light.
In order to get perfect and cheap glas hemispheres we reused old light bulbs.

Experimenting with the water filled light bulbs we found out that
- the distance between the bulb and the flame
- and the angle between the two of them
determine the size and point of appearance of the light focus.

Many people in Kangemi use candles and
cerosene lamps as a substitude for electric light.
Candles have a warm light color that is pleasant
for the eyes but the light is diffuse which makes it hard
to work or read at it.
My original attempt was to experiment together with Stacy and Kevin on ways of improving the light of candles in order to be able to build a lamp, driven by a candle, that could given an improved light when for example reading in the evening.
We started off with first experiments on the change of light in combination with different transparent and reflective materials and water.
For that the kids were supposed to collect materials as glas containers, bottles, can, metal foil and others that they could find around the area of Love School.
