Now in the trend to be seems ice as building material. So a hotel built of ice in Sweden recently opened. Students from all over Europe begin immediately after Christmas also with the construction of the longest ice bridge in the world. This should be built close to the Finnish city Juuka and arise from a total 900 tons of ice. The design of the bridge is based on a sketch by Leonardo da Vinci. The completion of the total 65 metres long bridge is planned for mid-February. Then, an international ice Festival takes place in Juuka, on the bridge of the record will be one of the main attractions.
However, the bridge does not arise from pure natural ice. Rather a mixture of 98 percent water and 2 percent is paper fibers used. The addition of fibres thereby ensures that the frozen ice is later about three times as stable as ordinary ice. The water-fiber mixture is then applied in thin layers on a giant balloon and then freezes. At the end of the balloon is removed and there is a bridge that is self-sustaining. Its stability should be made then proves, by opening to drive a car across the bridge. Then, then pedestrians about the longest ever built ice bridge can stroll. This a free space is bridged about 35 metres.
The project is organized by the Technical University of Eindhoven. Locally, then about 150 volunteers from all over Europe are used. The working conditions are anything but enjoyable. So the work must take place around the clock, because otherwise there is a danger that the needed equipment to freeze. A night shift is not for frostbite in the depths of winter of Finland with security. Originally was even planned to bridge a free space of fifty meters. However, calculations showed that the required amount of ice can be produced not fast enough.
