Hold the barrel at an angle.
If the barrel is half full the wine will go from one end to the exact opposite (in all 3 dimensions).
If the wine level is lower, the barrel is less full. If the wine level is higher, the barrel is more than half full.

Two people are traveling across the country. They both leave from the same city, and both have the same final destination. They also both leave at the exact same day and time. One travels by bus, and the other by aircraft. However, the bus passenger arrives before the passenger on the aircraft.
How is this possible?
