Prof: So we can use this to find out that
Me: But the problem is it becomes bloated, something like thermocol... So I don't think this will work
Prof: Thermocol? What's that?
Me: :-8 (wondering if I would be technically correct to say if it was polystyrene, I was unsure, which it was as I later discovered)
Prof: Do you mean styrofoam?
Me: Yes, yes, styrofoam(correctly guessing it was something similar)... We call it thermocol in India
Prof: (chuckle chuckle)
