Rock Balancing Optical Illusion

These fine rock creations are the art work of Bill Dan of San Francisco, California. The title above suggests that these rocks are balanced, just sitting there waiting for someone to topple them over. What do you think? When you are done pondering how this was accomplished you can click the link below the picture.

How about the photo below. It would seem impossible to believe that these are balanced. Look at the center stack, there is no way those rocks are balanced. Right?

So what do you think is the mysterious force holding these rocks in place?

Ok your right the center stack was photographed in mid fall. A split second prior to this photo being snapped they were in balance but the earth is spinning at about 2,000 miles per hour. At that speed it is amazing that any of us can balance.

I think they were photographed on the ground then added

you'r wrong. earth spinning doesn't influence ballance, since you (and everything else) is spinning with it in the same time... so your physics isn't very well (it's basic principle)

coreoles force does influence it, but it's somehing different that influences moving bodies. read some books...

it was done probably by photoshop or by insering steel poles, bars through the objects so we don't see them.

Let me be clear. The spinning earth was "a joke". These rocks are balanced and held in place by gravity. There was no photo trickery or steel rods or glue. If you go to his site he has many videos of putting the rocks in place. There are also many rock balancing groups/clubs around the country as a result of his work.
