Here is a neat experiment making the guy in the video feel like there is no or very little gravity on the wheel he is spinning.  Many of us have spun gyroscopes and seen them balance and this is much cooler in the large scale.  It is called gyro precession and here is a bit more about the video:

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.

Let’s see how this thing works in the video on page 2
