How to Create a Solar Bottle Bulb

How to make your own Solar Bottle Light Bulb?



The materials are the following: 1.5 liter soda bottle, 1’x1’ roof sheet material, purified water, camera film dispenser, chlorine and a rubber sealant.

Procedure:

Step 1. Fill the 1.5 liter clear soda bottle with purified water then add 3 tablespoons of liquid bleach and tightly seal the cap. Do not use tap water because this will allow the growth of moss.

Step 2. Make a hole in the 1’x1’ roof sheet material, just the same size of the bottle’s circumference and insert the bottom part of the bottle leaving it exposed under the sunlight.

Step 3. Next, make another hole on the roof of the house (same as the bottle’s circumference) where you want to put the solar bulb and firmly fix the device.

Step 4. Seal the roof with a sealant to prevent raindrops from getting inside the house. It will produce a light when the water inside the bottle bulb refracts and scatters the light inside the house.

The solar bulb is expected to last up to two years before it needs changing.
