Pineapples are a common street food in SE Asia, so finding a way to increase production increases profit.
This Malaysian street vendor has it down to a fine art:
Why are we still peeling pineapples like cavemen? 🛠️🍍This gadget does it perfectly in seconds. Lazy? Maybe. Smart? Absolutely.#pineapplehack #funnyvideo #asmrcooking #foodhacks #cooksky #beestrot

Typically hand-peeling to get this artistic result takes 2-3 minutes, but this gadget gets the job done in under 30 seconds.
From Harvard Natural Sciences Lectures
I found this fascinating and mesmerizing.
The period of one complete cycle of the dance is 60 seconds. The length of the longest pendulum has been adjusted so that it executes 51 oscillations in this 60 second period. The length of each successive shorter pendulum is carefully adjusted so that it executes one additional oscillation in this period. Thus, the 15th pendulum (shortest) undergoes 65 oscillations. When all 15 pendulums are started together, they quickly fall out of sync—their relative phases continuously change because of their different periods of oscillation. However, after 60 seconds they will all have executed an integral number of oscillations and be back in sync again at that instant, ready to repeat the dance.
