Dissecting a rat

Today's biology class consisted of dissecting rats. In my dissection, opened up the rat's skull to expose the brain. The brain was rather soft and was easily cut with a razor, so I had to use some caution. The rats were dipped in a formaldehyde-like substance that gave the rats a yellow color and made them smell bad. Unfortunately, despite wearing gloves, I got some of that substance on my hands, and despite repeated hand washing, my fingers still smelled like the dissected rat. This was rather annoying at lunch for whenever I brought my sandwich to my mouth, I could smell the preservative, which reminded me of the cut up rat. Not very appetizing...
