Was Savonious' Principal not similar? I have a jurassic memory of writing an essay about it back in the (19!!!)80'sWhen I was a nipper I was absolutely fascinated by the demonstration of the Bernoulli effect where you hang two ping-pong balls by threads so they rest about 2cm apart; then blow air between them using a drinking straw. The results were so different to what I expected.
