An incredible natural stone, worthy of a world record, was passed on to Mr. Lai Jianhua (Zhuzhou, Hunan Province). The stone weighs about 3.5 kg, measures 24x13x9cm and is composed of solid beeswax, silica and basalt. Its bottom curve is rather peculiar, with three naturally formed support points. As a result of a human touch, the stone can swing for up to 140 seconds, for a total of 258 swings.
