I shined a flashlight through one of my glasses filled with tap water today and I was amazed to see that it too generated a rainbow !!
This is in our drinking water people !!! I've been trying to get funding all day to get a national campaign rallied up, but I have yet to be too successful ! Don't people care about what they're drinking ?
I even ran the water through a filter pitcher, poured it into a glass and got the same effect when I shined the light on it !!! Not even the water filters can get this chemical out of the water !
