Decorating your lab cover is optional. You get nothing for doing it aside from the amusement of creating something your friends will chuckle at (or WOW at) when they see it up on the bulletin board outside Rm 109. And you don't even have to be a good artist. A stick figure and a clever thought is all you really need. In any case, what follows are examples of lab covers that were done by people with WAY too much time on their hands, who got into the swing and spirit of the things, and who have over the years generated some interesting and artful fun.
kindly note: if you magnify the above cover, you will find a subliminal message--something about a sacrificed pig--cleverly inserted underneath the "sugar and spice" message on top . . . fun stuff!!!
Hopefully you found that amusing. Caio bella!
