Note: Just watch the video,it's worth it.
This is a video of the cake serving Rube Goldberg machine that Joseph of Youtube channel Joseph's Machines spent three months perfecting. It's pretty genius from start to finish. I especially liked the butter melting slide. Oh, and the laptop and flower pot destruction -- but that's just me and I like breaking things. I've actually been to one of those 'infuriate rooms' where you pay to fracture dishes and old televisions to let off a limited steam. "How'd that move?" Fantastic, or burnt the building to the ground.
Keep going for the video,it really is a treat.
