No I haven't, I didn't have the strobe equipment (or a fast enough camera) needed to do the experiment, unfortunately. However, I have read reports by researchers who have, and the Ranger rocket anomaly is known in the history of rocketry.

There are reports of I think it was Bowing who have been doing research on anti-gravity aircraft for several years now, using a high speed rotating body of liquid supercooled metal to achieve some sort of gravity manipulation using this principle and perhaps others.

Good luck with the gyroscope test. You will have to get it fast (the ball bearing test used 27'000 RPM) and then stand well back, I hear those things off aircraft can throw you across the room.... A 20 foot drop should just about do it I would think. I would have something soft for them to fall into ....
