Ortwin Grüttner: The most dangerous roller coaster marble run

Die neueste Kugelbahn Ortwin Grüttners , des Murmiland-Gründers zeichnet sich durch viele verschiedene Hebetechniken aus, die er auch wieder in ein Thema einbettet. Er schreibt dazu:

The most brutal roller coaster in the world:First the gripper grabs the passengers and throws them to the next floor. Then the passengers are transported upwards using various mechanisms. From there you go into the centrifugal funnel. Then there is a hammer blow on the head. And then you become dragon food. The marble run with the hammer.We remember the poor victims.
