Wood is good.
Incredible Wooden Marble Machine With Escalator

Marble machines: I’ve been making them since my age was in the low single digits. Granted those were all made out of children’s wooden blocks and the marble usually got stuck somewhere I couldn’t see, but I consider myself an expert on the subject nonetheless. This is a very impressive modular marble machine constructed by very appropriately named Youtuber Wood marble machine. A name with meaning, I like that. My name? My name means ‘God has given’ or ‘God’s gift’, which couldn’t be further from the truth. I love the sound this thing makes as it runs, it reminds me of rain falling. Or someone peeing. Am I peeing? I’m afraid to look. Will you look for me? “Are you wearing pants?” Will you look if I’m not? “No.” Of course I am, silly!
