At sea level you get more help from the ambient pressure to push the liquid into the straw; but this cancels out with the fact that your jaw, chins and tongue have to do work against the same higher air pressure in order to create suction. It's not as if "create an absolute pressure of 28 kPa inside your mouth" is as easy in Florida as it is on Everest.<br /><br />Assuming that the density and viscosity of the liquid do not change significantly with pressure, the same pressure <i>difference</i> moves liquid through the straw at the same rate, and the same tension in jaw/chin/tongue will create the same pressure difference.<br /><br />Since we're ignoring temperature differences, the only remaining effect seems to be that the liquid has a larger buoyancy in the dense Florida air, so it will take (very slightly) less work to lift it from cup height to mouth height.Henning Makholmhttps://www.blogger.com/profile/16299831550580392748noreply@blogger.comtag:blogger.com,1999:blog-12261589.post-81502663691211976372009-11-10T02:23:56.592-05:002009-11-10T02:23:56.592-05:00This comment has been removed by a blog administrator.Term Papershttp://www.ghostpapers.comnoreply@blogger.comtag:blogger.com,1999:blog-12261589.post-90625863486271009622009-05-26T23:12:29.002-04:002009-05-26T23:12:29.002-04:00Ah got it - smaller change in pressure due to lowe...Ah got it - smaller change in pressure due to lower external-to-the-straw pressure. Cool! <br /><br />I love a puzzle although I'm bummed I got it wrong; engineers tend to think only in inches of head pressure without reference to external pressure.

Matt has nailed it....Neil - full points for style!<br /><br />Matt has nailed it. A straw in a glass with one end sealed (in this case by your mouth) is essentially a barometer. The pressure at the top of Everest is low, so you get less "help" pushing the liquid up the tube. (Kathryn, the liquid in the straw would rise less above the surface of the liquid under lower external pressure.)<br /><br />Overall, I'd rather be in Florida than at the top of Everest for a plethora of reasons!!

The change in pressure needed to change the liquid level a fixed amount (the amount the straw is above the surface) is the same whether on the beach or on a mountain.Kathryn Jhttps://www.blogger.com/profile/16757414380685368592noreply@blogger.comtag:blogger.com,1999:blog-12261589.post-12310135467546619452009-05-11T14:32:00.000-04:002009-05-11T14:32:00.000-04:00Well the density of the liquid doesn't change but ...Well the density of the liquid doesn't change but the pressure of the air does. At altitude, air pressure is lower than at sea level. Therefore, the pressure in the mouth needs to be reduced by a greater amount than at sea level because there is a lower atmospheric pressure to push the liquid up the straw. It is harder to drink a liquid through a straw at the top of Everst than on a beach in Florida.Mattnoreply@blogger.comtag:blogger.com,1999:blog-12261589.post-83977697711698281422009-05-11T11:15:00.000-04:002009-05-11T11:15:00.000-04:00The atmosphere is more rarefied at the top of Mt. ...The atmosphere is more rarefied at the top of Mt.
