I got the 21 questions at the grocery store the other day while buying less than a pound of dry ice. The girl apparently wanted to have a conversation.
Cashier- "What are you doing with it?"
Me-"Just a project for a class at UF..."
Cashier-"What kind of project?"
Me-"Uuh... Just an extra credit project..."
Cashier- "Ooh. For what class?"
I think I sighed a little too loud and she mistook my stumped eye boggle for something rude. I didn't really want to tell her I was Co2ing 30 something rats and sticking them in my freezer for later.
They also like to ask me how old my "child" is when I am buying size 1 diapers. I have to tell them it's for the Opossum. I really hope I don't look like I just spit out a kid.
So, what do normal people do with dry ice that isn't going to lead to a lot of questions?
