Antigravity 1989 Levitation Device

The standard Antigravity 1989 Levitation Device will have a normal lifting power of 1 ton of weight that can be lifted up to three (3) feet off the ground.

Then the object can be moved to another location while still being suspended in midair, called floating.
   Like a surf board skimming across the surface of water.  It's weight value of zero is then equal to the height of levitation. 
Anti-gravity can be used in construction, road obstruction and shows.
This is the same way they built the pyramids approximately 12 thousand years ago.
Antigravity 1989 is not a force, but rather a condition of (controlling gravity).
