Question

To prevent the degradation due to sunlight, some material are stored in which type of bottles?

Answer 1

dark coloured bottle which prevents them from reacting

Answer 2

We can make a bottle yourself at home. Just fill a translucent bottle with water, add a splash of bleach to prevent algae from growing in the bottle, and cut a hole in your roof—then slip the bottle through the opening. Make sure you seal up any cracks to prevent the roof from leaking, and let the sun shine in.

Painting the bottles with dark colour will also help keep the materials away from degradation.
