Confuse Traffic Signs

A cop pulls over a carload of nuns.
Cop: "Sister, this is a 65 MPH highway -- why are you going so slow?"
Sister: "Sir, I saw a lot of signs that said 22, not 65."

Sister: Oh, we just got off of highway 119.

This process could produce ammonia on a large scale directly from its component gases, hydrogen and nitrogen, by passing a mixture of them over heated finely-divided osmium metal used as a catalyst. A typical pressure of 175 atmospheres and a temperature of 550ºC could easily give an 8% by volume yield of ammonia. Although nitrogen makes up 80% of the air, as a gas it is quite unreactive. Despite its ready availability, nitrogen gas had previously been difficult to combine in a chemical form. Once nitrogen has been chemically combined in the form of ammonia, many other nitrogen compounds can be made.«
