So I was in the stockroom and a girl came to the window and picked up a disposable pipet.
Lab girl: Is this the capillary tube used for the melting point apparatus?
Me: No, that's a pipet. The melting point tubes are by the balances.
Lab girl (confused): Oh, right. The balances? Are they over there? (pointing toward the balances)
Me: Yes.What I wanted to say was...
First, please don't stick that pipet in the melting point apparatus, unless of course you want to find the melting point of plastic and then clean it up.
Second, we have been using melting point tubes nearly every week since last August!
Third, we have been using disposable pipets nearly every week since last August!
Forth, we have been using the balances nearly every week since last August!
Have you been in this class since last August?
