Tennis is a well known racket sport which is played by at least two people each usually using a different tennis racket strung together with string. Each player utilizes a tennis strung with thin cord to hit a small hollow rubber ball firmly covered with felt on top or over a specially made net in or near a tennis court and into the other opponent’s court. Each time the ball is hit, the tennis racquet generates a small but powerful “tsipping” motion as it makes contact with the ball. This action of the racquet sending out this low velocity energy into the ball generates a fraction of a volt of electricity. With this power source, these tennis racquets are ideal for research and medical laboratories where scientists can perform complicated lab experiments and study cells, viruses, and chemicals without fear of the power going out.
A popular type of tenis is the Tenis Microtennis, a ten-piece rackets set designed for rapid setup and take down. It includes a table tennis ball, a shuttlecock and a base. It also includes a carrying case for easy transportation. The Microtenis is the fastest type of tenis available and is often used in schools to teach kids how to play the game and in clubs to compete against other players. It has been successfully used by professional tennis players to win numerous prestigious tournaments such as the United States National Team Open and the Australian Open.
Since the invention of the Microtenis tenis has evolved into a highly versatile piece of equipment. A number of variations of the tenis exist, including battery operated and manual wind versions. Other variations have been developed to add a battery or wall adapter to allow for use outside or in areas that do not have outlets for standard sized table tennis sets. The original teni was originally invented in eighteen20s at the University of Glasgow in England. It was invented by William Campbell who developed it to be a more convenient alternative to a portable lawn tennis court. Today, tenis are still an extremely popular choice for use in both indoor and outdoor sporting venues.
