My ex worked at a children's museum where they'd regularly make this stuff in quantity for kids to play with. It looked like a lot of fun. It surprises how few adults I encounter have any idea what I'm talking about when I mention it by name describing something behaving like a non-newtonian fluid. For example recently I was telling someone how deceptively epoxy that seemed thick and extremely viscous while mixing will slowly but tenaciously flow through the tiniest of gaps in a mold or dams as if it were water. I've found JB Weld in particular behaves a bit like a non-newtonian fluid while stirring it up before application, seemingly solidifying more the faster it's stirred, then turns runny when still until curing sets in...
