Fun puzzle, thanks Param!

They spin horizontally and vertically and when the clamps release them they are 4 inches taller.

They are enjoying a new amusement park ride in zero gravity. It spins slowly so their feet are strapped into special boots that are permanently attached to the ride. The ride stops & starts, oscillating gently, and dance music plays in sync with the motion of the ride. :-))

Thanks sunnydays.
You're welcome.
