Roller coaster

A roller coaster is an amusement ride developed for amusement parks and modern theme parks. LaMarcus Adna Thompson obtained a patent regarding roller coasters on January 20, 1885, which were made out of wood, but this patent is considerably later than the "Russian mountains" described below. In essence a specialized railroad system, a roller coaster consists of a track that rises in designed patterns, sometimes with one or more inversions (such as vertical loops) that briefly turn the rider upside down. The track does not necessarily have to be a complete circuit, as shuttle roller coasters demonstrate. Most roller coasters have multiple cars in which passengers sit and are restrained. Two or more cars hooked together are called a train. Some roller coasters, notably wild mouse roller coasters, run with single cars.

History

Russian mountain

The oldest roller coasters are believed to have originated from the so-called "Russian Mountains", which were specially-constructed hills of ice, located in an area that would later become St. Petersburg. Built in the 17th century, the slides were built to a height of between 21 and 24 m (70 and 80 feet), consisted of a 50 degree drop, and were reinforced by wooden supports.

Clapping game

A clapping game (or hand game) is a type of usually cooperative (i.e., non-competitive) game which is generally played by two players and involves clapping as a rhythmic accompaniment to a singing game or reciting of a rhyme, often nursery rhymes. Clapping games are found throughout the world and similar games may be known throughout large areas with regional variation.

Nature of the games

Due to the communication skills and coordination required, simple clapping games are age appropriate for children age 24 months and above. In many cultures clapping games are played by both sexes and all ages, but in many European and European-influenced cultures, they are largely the preserve of young girls.

Claps commonly included in patterns are clapping one's own hands, clapping both hands of a partner, and clapping one hand of a partner, generally across such as the right hand of each player. The clapping may include other activities such as thigh slapping, or a final move such as touching the ground and freezing. Sara Bernstein describes seventy-nine "basic hand-claps".
