Mais uma vez o sul de itália está em maus lenções.

AN ice disc usually found in polar regions has been seen on a British river for the first time.
The 10ft perfect circle was spotted spinning along by two ramblers following the cold snap.
The discs form when tiny whirlpools are created under a frozen river by a reverse current.
The force of the vortex cuts through the ice and the circle breaks free.
But they are so rare, they have no scientific or meteorological name.
