Question of existence of chemical

[scampy74]

Hello,

I have heard that there is something you can put in pool water that detects urine and forms a color cloud around the area and also around the person that did it. I have also been told such a chemical does not exist, so I'm confused at to who to believe.

Does anyone know if it exists, and if so what the chemical is called and whether it is relatively inexpensive? This is not a must have; more of a practical joke on some friends.

Thanks for any help.

Pure urban legend. A full debunking can be found on snopes.com.

What about a container of blue food coloring? You could put it in your pocket, take it out and empty it and put it back in your pocket. Then you could say "Aaaaahhh, much better." and watch everyones expressions. Priceless.

Thanks for your help! I was a little suspicious of this but I thought it'd be funny nonetheless. I could try the food coloring idea, that would be funny as well, however I was more hoping that I could catch a friend peeing in the pool and then having a cloud follow them around which would just be priceless.

Thanks for your help everyone!
