It has been said by historians that the Russian Ice Slades were the roller coasters origin. These slides previously showed up amid the seventeenth century all through Russia, with a specific focus in the territory of in what might move toward becoming St. Petersburg. Lumber and a sheet of ice several inches thick were used in the process of building the structure of the ice slade. Riders climbed the stairs appended to the back of the slide, sped down to a 50 degree drop and rise the stairs of the slide that laid parallel (and inverse) to the first.
The slides picked up support with the Russian high society and some were luxuriously enlivened to give diversion “fit for royalty.” It is said that Catherine the Great was an extensive fanatic of the rushes given by the slides and had a couple based on her own property. Amid the winter celebration season slides were worked somewhere in the range of seventy and eighty feet high, extended for several feet and obliged numerous expansive sleds without a moment’s delay.
There is an ongoing dispute as to who added wheels to the equation, obviously creating the first roller coaster. Some think it was the Russians, other’s believe it was the French who came up with the idea. Robert Cartmell gives the Russians credit for building the first wheeled machine in his popular book ‘The incredible scream machine: A history of the roller coaster’.
It is known that by 1817 two coasters were built in France called the Les Montagues Russes a Belleville and Promenades Aeriennes, both of which featured cars that locked to the track in some manner. The very first looping coaster was situated in Frascati Gardens in Paris, France. The slope was 43 feet high, had a 13 foot-wide loop and was tried with everything under the sun before people were permitted on. The format was straightforward: the rider rode down the delicate slant on a little cart and through a fairly small metal circle.
