Melody roads that play music as you drive

A Japanese engineer by the name of Shizuo Shinoda accidentally scraped some markings into a road with a bulldozer and drove over them, and realized that it was possible to create tunes depending on the depth and spacing of the grooves. In 2007, the Hokkaido National Industrial Research Institute refined Shinoda’s designs to create the Melody Road. They used the same concept of cutting grooves into the concrete at specific intervals and found the closer the grooves are, the higher the pitch of the sound; while grooves which are spaced farther apart create lower pitched sounds. Today, musical roads are known to exist in six countries: Denmark, Japan, South Korea, the United States of America, Mexico and San Marino.

Apollo astronauts who orbited the moon two months before Neil Armstrong’s famous 1969 landing heard mysterious and unexplainable ‘music’ on its far side, out of the range of Earthly radio transmissions, it has emerged. Recently unearthed recordings made by NASA of the journey, which took the Apollo 10 capsule around the far side of the moon, show the astronauts reacting with surprise and confusion to an unearthly howling noise in their headsets. The sound began once the capsule was on an hour-long trip around the far side of the moon, out of the range of any Earth broadcast. At one point the baffled astronauts can be heard discussing whether they should tell NASA command or not.
