Edward Leedskalnin’s Ball Bearings

Origin
Edward Leedskalnin was an eccentric Latvian emigrant to the United States and amateur sculptor who single-handedly built the monument known as Coral Castle in Florida. Made to commemorate his sweetheart, he constructed all the structures, carvings and furniture out of coral. While giving tours of his creation, Leedskalnin would never explicitly state how he constructed the whole park. Sometimes he accredited a special form of reverse magnetism or paranormal abilities to brush off how moved structures weighing several tons and accurately crafted the supports without mortar.

One of the more prominent features was an 8-foot tall gate able to fit within a quarter of an inch of the walls. It was so finely balanced a child could open it with ease. The design of its perfect axis remained a mystery until damage forced crews to repair the balancing system. They discovered the center contained a metal rod attached to a truck bearing, which had rusted out and prevented it from turning.

Effects
Placing a bearing upon dirt, soil and other forms of earth will cause rocky structures to sprout from the ground like seeds. The growth will move outwards at a rate of several inches per hour, reaching heights over ten feet within a few days until it stops. During this time, the material is porous and feels spongy yet immediately hardens on impact. Each structure will slowly turn from basic block-like obelisk into a simply designed form of architecture (e.g. bench, shack, garage, tower). A temporary magnetic field will be created during growth capable of heavily altering existent electrical fields nearby.
