This seems backwards. Am I missing something?
- SiempreViernes 3y agoThe defining feature of oobleck is that if you try to move through slowly it is just a goopy liquid, but when you try to move fast the oobleck becomes hard (then because it is hard you get stuck as long as you keep pushing). I guess the bit you were missing is that the period when layers slide quickly over each other is (in my experience) very brief: typically the experience is your spoon almost immediately gets stuck and further pushing will break off chunks of oobleck, not push it aside.
- junon 3y agoThis is from the part where viscosity is mentioned though. I didn't take it to mean it was about oobleck specifically.
