After watching the video on Light in a bottle by Isang Litrong Liwanag Foundation , we tried to recreate this.
Requirements :-
1) A clean transparent bottle.
2) Pure drinking water.
3) Bleaching powder.
4) Dark room environment.
Steps :-
1) Put the water and bleach powder into the bottle. Stir it well and then seal the lid.
2) Put the bottle in a dark room environment, with upper half above the environment and the lower half in the environment.
3) Expose the upper half of the bottle to the sunlight.
Results :-
1) The fluorescent light generated was awesome. Check the link
* Notes :- Need to find out the duration for which the bottle continues to glow without adding further bleach powder.
