I find it hard to extrapolate from this experimental setup to an egg drop competition. A ~1cm drop onto a hard surface is quite different from a ~10m drop in protective packaging.
- hinkley 1y agoHowever you try to pad it there will end up being a hot spot where either the force is maximal or the shell is thinnest. So I think it makes sense to do the unprotected tests to see what the failure mode is for the egg and then design for that. The neck is the weak point in a car crash. So we design cars and airbags and child seats to account for that.
- javman 1y agoI wonder if someone made a mistake with unit conversions... The next paragraph says: > The results: over half of the eggs broke when dropped vertically from an 8-millimeter (31-inch) height 31 inches is 0.8m, not 8mm. Maybe they meant to say 0.8, 0.9, 1.0 meters? Strange.
- SamBam 1y agoYet the image ("Experimental snapshots for vertical (top) and horizontal (bottom) egg drops.") definitely appears to show something closer to 8mm, assuming the black area is the table. Edit: Reading the paper [1] it's definitely 8mm. The ArsTechnica writer screwed up the conversion to inches. Should be 0.31". 1. https://www.nature.com/articles/s42005-025-02087-0 https://www.nature.com/articles/s42005-025-02087-0
