A trampoline is for jumping and bouncing. 
It has a strong mat. Many metal springs hold the mat. The springs help you bounce high. 
People use them for fun. Some people use them for sports. They can even do flips in the air.
Astronauts used them for training. This helped them learn how to move in space.
Today, many people visit trampoline parks. These parks are indoor places for jumping.
A trampoline is a device used for jumping. 

People have bounced on fabrics for a long time. The Inuit people used a walrus skin for a dance. They would toss dancers into the air. In 1936, George Nissen and Larry Griswold built the first modern trampoline. They used a canvas mat and metal springs. The name comes from the Spanish word "trampolín." This word means a diving board.
Many people use trampolines for sport. It has been in the Olympic Games since 2000. Skilled athletes can jump very high. They do flips and twists in the air. 
Today, many people visit indoor trampoline parks. These parks are large places for jumping. Some use bungee cords to help people jump higher. Others use water trampolines for fun in the pool.

Building a modern trampoline takes careful engineering. A competitive model uses a rectangular bed made of strong webbing. This bed is held in place by about 110 steel springs. The steel frame is very sturdy and can often fold for travel. For fun at home, recreational trampolines might be circular or octagonal. These often use waterproof canvas or plastic materials for the mat. Some special types exist, like water trampolines used near lakes. These still use a spring and mat system to create a bounce. 
People have enjoyed bouncing on soft surfaces for a long time. The Inuit people had a spring celebration called Nalukataq. During this time, they tossed dancers into the air on a walrus skin. In the 1800s, firefighters used life nets to catch people. In the early 1900s, circus acrobats used small bouncing beds. These beds were often covered in bedclothes for comedy shows. Some stories say an artist named du Trampolin invented the device. However, there is no real proof that this story is true. 
George Nissen and Larry Griswold built the first modern trampoline in 1936. They were both students at the University of Iowa in the United States. Nissen did gymnastics and diving, while Griswold was a tumbler. They used a canvas mat with metal grommets and springs. Nissen took the name from the Spanish word "trampolín." In Mexico, he heard this word meant a diving board. In 1942, they started a company in Cedar Rapids, Iowa. This helped make trampolines available for everyone to buy.
Today, trampolining is a major global sport. It has been part of the Olympic Games since the year 2000. Skilled athletes can jump very high to perform many twists. NASA even used a game called Spaceball for astronaut training. This helped them learn how to move in different positions. Many people also visit large indoor trampoline parks for fun. 
A trampoline is a specialized device used for recreation, training, and high-level competition. 
Modern trampolines are engineered in several distinct ways to suit different needs. Competitive trampolines are built for extreme performance and durability. They typically feature a rectangular bed made of strong webbing material. These professional models use approximately 110 steel springs to maintain tension. The steel frames are sturdy and often designed to fold for easy transportation. In contrast, recreational trampolines are intended for home use. They are often circular, octagonal, or rectangular in shape. These models use weaker springs and mats made of waterproof canvas or woven polypropylene.
There are also specialized versions of the trampoline designed for unique environments. Bungee trampolines are common at fairs and summer camps. These use bungee cords to help inexperienced jumpers perform flips safely. Water trampolines are inflatable devices used near lakes for swimming recreation. They still follow the standard principle of using a spring-held mat to create a bounce. Some commercial facilities use wall running setups. In this sport, participants use platforms next to the trampoline bed. This allows them to transfer vertical speed into rotation by touching a solid wall at the peak of a bounce.

The first modern trampoline was officially invented in 1936. George Nissen and Larry Griswold built it while studying at the University of Iowa. Nissen was a gymnastics and diving competitor, while Griswold was a tumbler. They experimented by stretching canvas with metal grommets onto an angle iron frame using coiled springs. Nissen chose the name from the Spanish word "trampolín," which means a diving board. He had heard the term during a tour in Mexico in the late 1930s. In 1942, they formed the Griswold-Nissen Trampoline & Tumbling Company in Cedar Rapids, Iowa.
