I'm not always down with Mark Rober's videos. He tends a bit much toward goofy, seemingly-feigned excitement for my tastes, and he tends to bring this out in Destin, too. I'm starting to see a trend in YouTube videos that could easily be made about 30% shorter if they'd just edit out the people going "Whoa!!!!!!!...Yeah Baby!...Look at that!".
But...
To hit the serious matsci/science content in bullet points here...
- 6:25 - compressed golf ball with elastic deformation
- 7:05 - "The ball is hot." - transformation of kinetic energy into thermal energy
- 7:30 - destructive testing and inelastic deformation
- 7:40 - Destin actually says, "an area of physics called material science" and demonstrates elastic and plastic deformation with a 'force-distance' curve (pretty much a stress strain curve). He also compared the curves for a generic metal and a generic plastic, then real and practice golf balls
- 9:15 - We see a plastically deformed but still intact golf ball, one that was hit somewhere above 300 mph against the anvil.
- 10:05 - 50-year old golf ball hits the anvil and is obliterated, apparent source of the apparently-color-enhanced video still above
