Hubelino Rutsche - Wie funktioniert dieser coole Effekt?

Here it is, finally, my review of the Hubelino slide extension, number 420640. Four bright orange plastic tracks with a great spinning effect for the balls. The balls are slowed down on the track and glide down with rapid rotation – and at the end of the slide, they are catapulted forward. But is it worth twenty euros? Decide for yourself!
