This guy unicycled along the edge of a giant dam

The Vidraru Dam in Romania is 545 feet tall, but daredevil Flaviu Cernescu saw this as an invitation to ride his unicycle along its narrow ledge — watching him will make your palms sweat.

His GoPro video shows him standing on the ledge, juggling, before hopping on his unicycle.
