In this video a tall biker and a woman who appears to have average height get measured in a relative height method standing apart from each other.  The guide shows that the ground is level by using a contractor’s level bubble and it appears to be at a flat angle.  When they switch places and you view their relative heights, the biker appears to become way taller than the woman.

Is this an illusion, bogus, a trick or a real vortex that we can’t explain?  If nothing else my curiosity is piqued and want to try this out.  Just a note Maria Cooper states that the vortex and house of mystery are two seperate things.  They also try a gravity test with some rolling balls and they seem to defy gravity and move at a slower speed that other places on planet earth.  If indeed there are no magnets etc under the place where they roll the balls I would believe this..so who knows?
