10. PREPARE THE BOTTLE
The solar lamp is compatible with any soft drink
bottle cap. Take an empty soft drink bottle and
clean it thoroughly. Fill the bottle with water and
add a few drops of chlorine bleach to prevent
algae formation and keep the water clear.
Close the bottle with the Solar Bottle Lamp
(Figure
R
) and your lamp is ready to use!
