A remote road rest area in Poland has become host to a unique phenomenon: bottles and cars rolling up hill instead of downhill.
The earth’s gravitational pull appears to have been simply suspended at this location. Bottles start to roll uphill of their own accord – but why? There are various theories being bandied about to explain this “gravity anomaly”. Some observers believe it is the work of witches and trolls. There are also, however, rather simple physical explanations for the phenomenon, such as subterranean water veins.
