Special Track Marble Run

30 years ago, I started building various marble runs.
This marble runs can be played at various events.
For my 30th anniversary, I had planned a very large exhibition.
I designed and built a special track especially for this exhibition.
I developed the gravity catapult elevator on this route from scratch.
The exhibition has been canceled due to the spread of the corona virus
Now I have improvised and set up the track in our garden.
So that it can be put into operation for at least one day.
Thanks to all friends who remain loyal to us.
