If you spin a gyroscope, it will slowly sink to the floor. But if you spin it VERY fast, see yourself!

This is a TEDCO "Original Gyroscope" lubricated with vegetable oil, winded up with a 120 cm long kite cord (included original cord is too short for such high speed spins) - and given a strong push.

It starts with approx. 12.000 rpm which is a circumferential speed of 77 mph.

You can watch the full run. It starts with a lot of noise. A considerable air draft can be heard during the first seconds. At 1:22 you see for a few seconds, that the lying but still spining gyro produces some sort of weak propulsion. I think this is due to vibration. This propulsion effect is stronger if the gyro is forced to lie down at higher rpm.

Second half of video is just for those who would like to know how long the gyro spins until it stops.
