you can oppose gravity, but you cannot neutralize it.

Let's compare the force of gravity of earth to the force of
electromagnetic interaction of electrons:

Take a balloon,
rub it against your hair,
put the balloon close to the ground,
pick up an ant with electromagnetic interaction,
Gravity loses.

If this were "anti-gravity" then patents would be used for wallpaper.

appearing on WikiLeaks?)
