Jeff, I did an experiment about 12 years ago at China Lake. We had a centrifuge, 2 meter radius. I and some guys were arguing about what would happen if you put an egg in a bucket of water in the centrifuge, would it sling to the bottom or continue to float? I argued that if the eggs were floating in 1 G, they would float in 100 G.

I bought a dozen guppies, put em in a plastic thermos bottle, put the bottle in the centrifuge and spun em up to 100 g for 10 minutes. When I stopped, all the fish were still alive, but were swimming in a spiral pattern, like a well-thrown football. {8-] Please dont turn me in to the animal rights people. {8^D spike
