Must share what I have been doing. I went shopping and got a small packet of bleaching powder. Finding empty plastic water bottles in the house was no problem. I put three table spoonfuls of this powder in one bottle and four tablespoons in the second. Filled up both bottles with clean water. Tightly screwed the caps and hung those at different spots- each spot getting direct sunlight.
Alas nothing happened - no light, no refraction.
I must have made some mistake- either the quantity of bleaching powder used was more/less than required or my choice of spots was wrong....I dont know
Anyway I plan to retry again today.
PS. Friends (?) have already started making fun of me saying that I have been taken in by some prankster...
