What does licking bitter tasting paper test for?
« on: 23/02/2006 01:50:37 »
years ago in a high school biology class our teacher had us lick a piece of paper, if it tasted bitter we had (or were missing) a certain gene, or vice versa.

Does anyone know what paper it was or what it was testing for?
