I checked into the good news network and found an article on weird floating rocks. I seemed to have lost the original video which was very commercial yet fascinating with its pictures of precariously balanced massive stones.
The one I looked up is the famous Japanese floating rock - it isn't actually floating, but it is an arresting sight.
"The Ishi-no-Hōden is made from tuff and is surrounded on three sides by unprocessed bedrock. With a weight estimated at 500 tons, it measures 6.4 meters wide by 5.7 meters high by 7.2 meters in thickness. In shape, it is carved in the form of two flat rectangular parallelepipeds oriented vertically and sandwiching a small rectangular parallelepiped. One of the sides has a protrusion shaped like the top of a pyramid. The space between the surrounding bedrock and the megalith is wide enough for one adult to pass through, and it is possible to go around (admission fee is required). The monolith is situated in a large depression, which forms a pond at its base. The monolith is carved with a pillar at the center of its base, which is not visible at eye-level, so the monolith appears to be floating above the pond." |
