Cyclist with Portable Washing Machine

the prompt

A young Japanese businessman in a suit commutes on a bicycle down a sunny, quaint residential street in Japan. He wears a large, white, spherical portable washing machine on his back, which spins rapidly. The camera follows him from behind, then pans to a front shot as he looks back intently. The scene shifts to an older professor in a lab coat explaining centrifugal force on a blackboard, then back to the businessman proudly holding a clean white shirt and giving a thumbs up outside a building. Bright, cinematic, commercial style.
