Last week in lab, after we had passed safety inspection:
Me: What is that terrible smell?
Labmate: I’m burning plastic.
Me: Um, why are you burning it with a soldering iron?
Labmate: Because if I got out the drill, I would definitely lose a finger.
Me: Okay. What are the holes for?
Labmate: To attach tubes to this box.
Labmate: So I can run electricity through some water.
