I used to believe, after being told by a friend my age, that if you buried an ant with a chip of glass, that it would turn into a termite. We'd bury our ants one day, and come back and look for them a day later, and every time the ant and piece of glass were gone (or we couldn't remember where we'd buried them, more likely). One time we found a termite where we thought we'd buried the ant, so that of course proved it was true!
