The Pike Syndrome
The professor had the graduate students that were his aides bring in a table. Then he had them bring in a big glass fish tank. It was pretty big, about five to six feet long and about four feet high. Then he had them bring in the pike, which is a carnivorous fish—and then bring in the minnows. It was a pretty convincing act. The pike eats faster than the human eye can react to and calibrate what's actually happening.
