When I was in second grade, my sister (who was a kindergartener) and I used to believe that the little black seeds that dropped off of palm trees were actually cockroach eggs. In an effort to diffuse a cockroach infestation, we gathered them during recess at school (or wherever else we'd find them) and collected them into plastic drink containers.
Once we filled it up with "cockroach eggs", we'd seal it shut and throw them away.
