Extreme balance

Slackline is a kind of tight rope, but since the line has some give and is relatively wide (about 4cm or 5cm), it has developed into a kind of extreme sport. People can bounce in various positions, and if they are really good they can do flips. These guys were really good. They could do flips. Their shows are periodically in the daytime, near the Cafe de Paris. There is also a line where you can try for yourself and see just how hard this is.
