Great find @ 0:40. The only thing it doesn't convey very well is the older man's explanation of the copper spear curling outward on itself. From the simulation, it seems like it is just punching through and maintaining its rigidity somehow.
- jvanderbot 4y agoiirc, nothing is rigid, it's just very high energy jets, so they don't deform much. like particles in water jets cutting steel.
- itsyaboi 4y agoFun fact: water doesn't actually do the cutting, the water is just a medium for carrying an abrasive dust (ruby/sapphire/diamond) that abrades the steel.
