Thanks for you time with this! I hope you are finding it interesting, I certainly am. Are you suggesting that one single bubble fills the straw diameter, so there is a top surface, bottom surface and a surface clinging to the cylindrical sides of the straw? So when you say 'a straw with a...

So if there is not enough air flow or air speed to make this bubble form then you cannot suck anything up the straw?

So if this force is great enough it will push the liquid high enough to reach your mouth.

Ah, ok. I was looking into LaPlace pressure which talks about the size of the bubble and smaller diameters having higher pressure due to the 'pull' of the surface tension. Maybe that is getting ahead of myself? Ok, so each bubble will have a lower pressure than air because it is being generated...

Hi Haruspex, thanks for your reply! When you say bubble height, do you mean actual diameter of the individual bubble or the height relative to the ground?

Homework Statement This is not a set question but a problem statement for an investigation. I am trying to understand the physics behind drinking through a straw, but not when the straw is fully submerged in the drink but at the end of the drink when the liquid and air both pass up the straw...
