Robot Piano Catches Fire Playing Rush E (World's Hardest Song)
From Mark Rober
Summary
Mark builds a robot that plays an extremely fast, 'impossible' piano piece — so fast the machine overheats. It's a playful test of how far mechanical speed can be pushed.

A piano prop overheats and catches fire for comedic effect; controlled, brief. Made for a general YouTube audience — an occasional mild or bleeped word can slip in, so preview if your classroom bar is strict.

Talk about it
The robot presses keys far faster than human hands can, but running at the limit builds up heat. Engineers learn from what fails.
- Why can a robot play faster than a human pianist?
- What caused the machine to overheat?
- How do engineers use failures like this to improve a design?
Quick work-a-long
Vocabulary: mechanism, speed, overheat, limit.
Try it: Tap a rhythm as fast as you can for 30 seconds. What starts to fail — accuracy or stamina? Relate it to the robot.
