I have one of his simple experiments at home. All you need is a
bicycle wheel on a stick, so you can get it spinning up fast. We
built ours out of metal, and fixed an attachment on the wheel, so we
could use a drill to get the wheel spinning really fast.
Once you get the wheel spinning you only have to spin round a central
point with the stick extended, and the paranormal effects of
gyroscopes on gravity begin to occur.
If you mirror the direction of the wheel, and spin yourself around
clockwise, when it spins counterclockwise, the wheel ways less, and
tries to stand itself straight up, like a gravity compass.
If you spin the same direction as the wheel is turning it does the
opposite, and weighs more (pointing itself downward).
Here is a video of Eric Laithwaite preforming the demonstration
himself at a public lecture before he died:

I would recommend you save it to your computer. If you want to try
the demonstration, then I can send you out the same experiment that we
are making in our garage, very cheaply. An electric drill motor would
be suplied, but we can build the drill bits you need to attatch to our
wheel fixture and get the machine spinning at a high speed.
The other thing to note is that the faster you spin the wheel the
greater the effect, but also the faster the stick spins the wheel in
one direction or another adds even more to the anti-gravity.
No one has been able to find a workable model of physics to explain
this, or even really to find math that backs up why it happens. I
suppose that it is just like relativity, and time dialation. Except
it happens within the curvature of space and results in a gravity
dialation. And perhaps it is just that the actual mechanics of the
physics were never meant to happen in nature, unless we as humans
decided to run this experiment.
