Give a geek some cardboard, wood, and a roll of tape and he will cook up a very slick little obstacle course for said roll of tape. I don’t know what it is about this course that I find so mesmerizing.
I’m watching and thinking no way is that tape going to make it through the the slots cut in that cardboard, but it does. I could watch this video all day.
It sort of reminds me of the start of the TV show Elementary, but this clip comes from a classic Japanese kids show called Pythagora Switch, which featured all kinds of fun Rube Goldberg-esque machines like this. you can find more of them over on YouTuber KeN KeN’s channel.
