This interactive museum was the idea of a local entrepreneur, Dmitry Ivanov, who was inspired by a similar popular science project in Copenhagen, Denmark. Ivanov’s Amusing Science House occupies a part of the right wing of what used to be the Culture House of Fur Industry Workers. The museum has more than 50 interactive exhibits on display, illustrating the laws of physics – from optics to mechanics – in a plain and amusing way, including a fascinating plasma sphere. Some real historical machinery is also on show: an L-29 airplane, Mi-2 helicopter, and a KAMaz simulator – a gift of the President of Tatarstan. The museum hosts master classes and educational shows, where you can learn, among other things, about the son et lumiere effect, how to make toothpaste, cartoon drawing, and amazing properties of water. The History of Great Discoveries show traces scientific progress all the way back to the times of Aristotle. School Records is another show available here, which explains how to lift a huge load with the aid of two school books, and what such phenomena as torque, friction and static electricity mean.
