This afternoon I walked out onto my front porch and noticed an upside-down glass sitting there. I walked over to investigate. Under the glass was a dead daddy-long-leg spider. Also under the glass was a block of chocolate which was mal-formed and discolored and a green lego. Puzzled I went into the house to ask my son about it. I knew he had something to do with it - maybe because of the green lego.
"Oh that," he said. "That's a spider trap."
"So, you lured the spider over with the chocolate and green lego, and then you popped a glass over it?" I asked.
"Yep, that's how it works."
Hmmm. Maybe I ought to make a few of those for the basement.
