You’d think that hamsters would be better than marbles in this maze because they’re sentient mammals. However, I learned the hard way that that isn’t the case at all. One time, I grabbed a bunch of hamsters from a pet shop so that I could create a machine like this one using them. Since these are living, breathing animals with senses, I figured I could make them do whatever I want. But the dern things just wouldn’t cooperate! I tried everything I could to get the machine going, but they wouldn’t obey me.
If I had actually bought those hamsters, I’d ask for a hefty refund, and demand more cooperative, and less frantic hamsters.
