I am always astonished to discover that most people simply do not understand what streamlining is.

When shown a teardrop shape, most people (including his brother) incorrectly assume it will slip through the air better going pointy end first.
To demonstrate the difference between "pointy end first" vs. "blunt end first", his brother made up a brilliantly simple demonstration using a shop vac exhaust, a clear tube (the wind tunnel) and a model teardrop car.
car:
"windtunnel":
He compares the amount of time it takes the car to be blown out the tube depending on which way the pointy end is facing.
