6 pts) If you stick a straw in water, cover the end that is not submerged with your finger, and then remove the straw from the water, some water will flow out of the straw, but some will be retained at the very bottom. Once you remove your finger, the remaining water flows out of the straw. Please explain why water remains in the straw, and quantitatively describe (i.e., do a calculation) the conditions necessary for water to remain in the straw. A straw has a diameter of about 0.61 cm. Assume the depth of water retained at the end of the straw is 1 mm. [Note that this has nothing to do with capillary action – if it did, water would flow out of the straw after you remove your finger.]
