I remember making Rube Goldberg Machines when I was a kid. Most of my inspiration came from the American kid series ZOOM on PBS (did anybody watch that? Remember ‘Ubby Dubby’?!)
I remember I made one to squirt ketchup and let me tell you, those things take up a large amount of time, but most importantly, your patience. It’s impossible to get one to work on the first try, and if you were like me and used liquids (bad idea), it was just a hot mess.
But so much fun at the same time.
