Anti-Gravity Wheel?

Huge thanks to A/Prof Emeritus Rod Cross, Helen Georgiou for filming, Alex Yeung, and Chris Stewart, the University of Sydney Mechanical Engineering shop, Duncan and co. Ralph and the School of Physics.

In this video I attempt to lift a 19kg (42 lbs) wheel over my head one-handed while it’s spinning at a few thousand RPM. This replicates an earlier experiment by Professor Eric Laithwaite. He claimed the wheel was ‘light as a feather’ and could not be explained by Newton’s Laws. I wanted to find out for myself what I really felt like.

  1. you gotta love the title of this video – anti gravity wheel! i think gyroscopic wheel would have been better as there's no such thing as anti gravity! Anything that possesses anti-gravity should lift up, never to be seen again!

  2. That's how works the gravitational atraction between the moon and the planet. The moon would fall off to the planet if it wasn't thanks to the centrifugal force of the moon that maintains it spinning around the planet.

  3. It's not quantam physics. The centre of gravity is altered at the heaviest point. Therefore keeping a moment on the heaviest point alters it's actual down velocity direction

  4. Same basic concept of how flying saucers reduce gravity, except they use 2 counter-rotating liquid mercury masses at 60,000 rpm & frequencies. Its really cool!

  5. But in case of a pedestal fan its not satisfying bcoz the fan become heavier when the leafs are rotating (switch ON position )

  6. Dadurch das sich das Gewicht mit hoher Geschwindigkeit dreht ,wird die Kraft die im Zentrum wirkt nach aussen verteilt und man kann es besser heben .

  7. The next question is how much weight can you do that with before its actually too much and you start running into other problems?

  8. i would guess the same since it is still connected to him via his arm and the pole. also where can i see the result
