Handpulling Noodles to Teach Physics
If you like both noodles and science, you should get a kick out of this video from the physicist Philip Morrison's 1987 PBS show The Ring of Truth: Atoms, in which chef Mark Pi makes noodles to demonstrate the principle of halving:
After handpulling and folding the noodles just twelve times, Pi's created 4,096 strands so thin they're called dragon's beard noodles; Morrison points out that if Pi pulls and folds them another thirty times, the noodles would be so fine as to approach atomic thickness!
