K’nex + Marbles is my first ball machine that uses both K’nex balls and marbles. The pink/red marble track is Skyrail. In an upcoming post, I will give more details about Skyrail. Below is the video. (Sorry I couldn’t get the marble lift to work on this ball machine). Sorry, I forgot to take pictures 😦 . See if you can spot a sloth in the video.
Special thanks to:
Jelle Bakker- He introduced me to Skyrail.

Hello, we must tell you this construction project is amazing. Thank you for posting this movie. It is hypnotic to watch and we liked seeing the piano’s eyes, and we *think* we saw a sloth, but are not sure, upon review.
That looks great! I’m happy to see some of my things in it, I hope everything worked fine.
Thanks 🙂 Everything worked fine! I love your element and lift designs!
