hm, I don’t think so - non-Newtonian fluids are like water + cornstarch: they flow like a liquid unless you apply force, then they harden into a solid.
The tomato paste is just not a liquid, it’s so thick it functions like a solid. So if you spoon some of it into a jar, the paste will just stay where you spooned it, it won’t settle like a liquid would. AFAIK, a non-Newtonian fluid would settle like a liquid when not under force, unlike the tomato paste.













hm, that’s an interesting theory - I do think I’m able to get a sharper impact with the wet rag, there is no slow down before hitting the surface whereas maybe I’m not being as forceful but I’m also slowing down the jar more before hitting the hard surface? I guess that’s not that different than just using less force, right?
