Kit constructie sistem solar Kosmos KOS617097

The entire solar system in your own nursery. This ingenious model is easily assembled from over 50 pieces. The heart and impulse of everything is the sun: in it is incorporated the mechanics, which causes the planets to orbit in four different speeds and eight different orbits. Best of all, you don't even need a battery. The gearbox in the sun is a winding engine, simply rolling it, and all the planets from Mercury to Neptune move around the yellow center at different speeds. With a suction cup, the solar system can be joined to several surfaces. Close astronomy and special decoration in the children's room. A KOSMOS experiment kit for all children aged 8 to 12 who love starwatching or dream of traveling to space.
