When I was in college, we used to do experiments with mice. There was this one experiment in which we sent a mouse to a maze. First, the mouse had to finish the maze "normal style" and afterward, he had to finish it with a drop of Ginebra.
It didn't make sense back in the day because the time deficit isn't that lengthy.
I did pass the subject.
Anyway, I like the trapdoor setup rather than the rolling log and that spinning thing.
