I worked for 90 minutes today and nearly 60 minutes the other day (but did not put up a new video then). The latest:
While the Reversable Guy went to see what happened, the little brother grabbed onto the chopstick which had kept the stage from rotating properly. Before crashing into the ramps, he jumped off; he is fine.
Soon RG will go back to the switch and perhaps find the ramp knocked over, or maybe the ramp will turn the switch on full blast which could be fun..
Since June 2017, I have spent 6.7+ days on Marble Track 3.
The resulting videos available via https://mt3s.robnugen.com/ are like 8 minutes 46 seconds long.
