Some people walk on a thin wire. 
It is a hard skill. They must keep their weight over their feet. This helps them stay up.
They may use a long pole to stay steady. Some use a fan or an umbrella too. 
They can even dance on the wire. Some performers use hats or clubs. 
It is a very special skill. It is a fun thing to watch.
Tightrope walking is the skill of walking on a thin wire. 
Performers must keep their weight over their feet to stay up. They can walk "freehand" using only their body. Many use tools to help them balance. These tools include a long pole, a fan, or an umbrella. 
Walking on a wire high in the air is called highwire walking. If it is done outdoors between tall buildings, it is a skywalk. 

Tightrope walking is the amazing skill of walking along a thin wire or rope. 

To stay up, a performer must keep their center of mass over their feet. This is their support point. Some walkers go "freehand" using only their own bodies to stay steady. Others use tools like an umbrella, a fan, or a long balance pole. A pole helps by moving weight away from the center. This makes it harder for the person to tip over. 
There are different types of wire walking. Highwire walking happens at a much greater height than regular tightrope walking. If a person performs a skywalk, they are walking outdoors. They might walk between tall buildings or across a deep gorge. They might even cross a waterfall or a natural structure.
Many famous people have made history with these skills. Charles Blondin crossed Niagara Falls many times. Maria Spelterini was the first woman to cross those same falls. 
This skill is part of many cultures around the world. In Armenia, there is a tradition called Pahlavan games. These are dances and performances from a very old time. In Korea, there is a tradition called Jultagi. 
Tightrope walking, also known as funambulism, is the highly specialized skill of walking along a thin wire or rope. 
To perform successfully, an acrobat must master the physics of balance. The primary goal is to keep the performer's center of mass directly over their support point. This support point is usually their feet. When walking on the ground, a person has a wide base of support. On a wire, the base of support is drastically reduced. Highwire walkers often position their feet parallel, with one foot directly in front of the other. This makes their lateral support very narrow. Consequently, the walker must manage a side-to-side sway. The ankle serves as the critical pivot point for this movement.
Performers use various methods to manage their stability. Some artists perform "freehand," meaning they use only their own bodies to stay upright. Others utilize balancing tools to assist their center of mass. These tools can include umbrellas, fans, or balance poles. A long pole provides a specific mechanical advantage. It distributes mass away from the pivot point to increase the moment of inertia. This reduces angular acceleration, which means it is harder for the performer to tip over. By rotating the pole, a walker can also create an equal and opposite torque to correct their sway.
There are several distinct types of wire walking. Tightwire walking involves walking on a tensioned wire between two points. Highwire walking is a specific form performed at much greater heights. If a performance occurs outdoors at extreme heights, it is called a skywalk. Skywalks often take place between tall buildings, across gorges, or over waterfalls.
Equipment is carefully chosen to protect the performer. Most tightrope walkers wear thin, flexible, leather-soled slippers. These slippers protect the feet from abrasions and bruises. The suede or leather soles allow the foot to curve around the wire. In some cases, especially with softer rope fibers, beginners or hobbyists may walk barefoot. This allows them to grasp the wire between the big toe and the second toe. 
Many cultures have deep historical connections to this art. In Armenia, the Pahlavan games are a tradition of dance and performance. These games date back to the pagan period and are part of the Armenian theatrical heritage. 

History is filled with legendary performers who pushed the limits of the craft. Charles Blondin crossed Niagara Falls many times. Maria Spelterini was the first woman to cross those same falls. 
Modern performers continue to set incredible records. In 2014, Denis Josselin walked a 300-meter rope over the Seine River in Paris. He even covered his eyes halfway through the walk. In 2016, Maurizio Zavatta set a record for the highest tightrope walk performed while blindfolded. These feats demonstrate the incredible intersection of human skill, biomechanics, and courage.
