Eli5: why does the viscosity of a liquid determine the amount of pressure it takes to blow bubbles in it and does the depth of the liquid relative to where the air is released also play a role? (Is it harder to blow bubbles In deeper water?)

Answer 1

Viscosity also partially measures how strongly the particles of a liquid stick to each other. The more strongly they are attached, the more pressure you need to move them apart to create a bubble.
