Which one will fill first?
We’ve tested our Christmas puzzle in real life and we got a variety of different answers.
The result depends on the viscosity and flow rate of the fluid we use.
The official answer to our quiz is F but it could be L or A if we used different conditions.
We’ve used 4 different conditions to test our result
F
Newtonian fluid with viscosity as water poured at a low flow rate at room temp
L
Newtonian fluid with viscosity as water poured at a low flow rate at room temp with limited venting of the system
A
Newtonian fluid with viscosity as water poured at a high flow rate at room temp
A
Shear-thickening fluid with high viscosity poured at a low flow rate at room temp
