The below was taken from Jim Huck's blog.
"So when I tested, I had to pee in a cup, then mix two drops of the
urine and ten drops of water into a test tube. Then, I added the little
blue pill, and believe me, when they said that pill could cause severe
burns, they weren't kidding. The pill reacted violently with water, so
when you dropped the pill in the test tube, it would immediately
bubble, roil, and boil and heat the liquid to about 200 degrees F.
The liquid would change color. If it was blue, you were negative. If it
was green, you were spilling a small amount of glucose into your urine.
If it turned bright orange, you were most likely peeing honey."
