Tightrope walking is a highly skilled circus act. A tightrope walker has to walk along a thin piece of rope from one platform to another. It requires a lot of balance and concentration to make it all the way to the end of the rope. The tightrope is usually located high up, so there is a big fall to the ground if the tightrope walker loses their balance. There is often a net to catch anyone who might fall, but many tightrope walkers prefer to perform without a net. It takes years of practice to master the art of tightrope walking. A good tightrope walker can also perform other tricks, such as juggling while walking along the thin wire.
