churn

a butter churn

In the old days, milk trains consisted entirely of vans loaded with ten-gallon churns. When filled, these churns weigh 130 lb. each and their manipulation is an art. … Like the tank wagons, the churns are dairy property, but farmers often have other ideas, and find their own uses for them—it has not been unknown for dairy inspectors to find missing churns tucked away in an unsuspected corner of a farmhouse, filled to the brim with banknotes!

I wished my brain would shut up and knew that soon I'd have to start tidying, but first I needed to rest, so I tried to quell the pointless churn behind my eyes and kept on trying (in a minute) until Vicky came back home.
