Everyday physics & science demos Videos Recommended on Hacker News (125)
Everyday physics & science demos is one of the 150 topics Hacker News readers organize their video recommendations around. These 125 videos each earned real recommendations in real HN threads between 2009 and 2026 — 341 recommendations in total — and they're ranked by how many separate months the community kept coming back to them, not by view count.
Physics in everyday life: science demonstrations, Steve Mould, Smarter Every Day, slow-motion experiments, optics, sound and acoustics, fluid dynamics, counterintuitive science, citizen experiments.
Why HN keeps sending people here — on AT&T Archives: Similiarities of Wave Behavior (Bonus Edition): “By far the best introduction to the subject of waves of any sort.” — an HN commenter, 2019.
