Peeing blue
If anyone is interested in turning their urine blue in support of the blue paperclip project, here are some nice instructions. I am still accepting offers for the 1-year subscription to trade-ideas.com. Email me if you are interested.
It is as simple as just eating some Methylene blue:
A common prank amongst biochemists is to add small amounts of methylene blue (generally a few drops of a stain solution will suffice) to coffee, cola, or another dark beverage. The stain’s color will be masked by the beverage, and its taste is fairly faint. Within a few hours, the methylene blue will have been removed by the prank victim’s kidneys, causing his urine to change color. The urine may become green if little methylene blue was added; larger amounts create a deep blue color.
