I found a black widow on my desk a few hours ago, and ran out of my room, grabbing a jar. I put it in the jar with a few breathing holes on the cap. How? Trapping. I decided to name it Blackie. I've been feeding it flies by catching them with tweezers and forcing them in before the black widow can climb out, and slam the cap on.
Its pretty cool, and I think its a bit tame, since I put it in a pretty big jar and its moving freely, and hasn't tried to get out, or poke a leg out of the holes.
[update]: Blackie has now been squashed, and I may die.
[Update]: I am currently posting from a DS, and I am hospitalized. I'm going to be ALRIGHT.
