In the first season of Star Trek TNG, Data and Riker are looking through a porthole onto the bridge of a dead ship. The bulkhead has been blown, exposing the compartment to space. Riker says:<br /><br />"They were all sucked out into space."<br /><br />Data replies:<br /><br />"Technically, they were blown out, sir."<br /><br /><br />The water in the cup does not go up the straw because your mouth is sucking it up. Instead, your mouth lowers the air pressure in the straw. The air pressure on the rest of the liquid in the cup PUSHES the water up the straw.<br /><br />Try this: Take the same cup, but put an air tight lid on it with a hole in the center to put the straw. Suck on that. How much water do you get?<br /><br />Here is another question. Take your "earth straw", but start it out in space so that it contains a vacuum. Cap both ends, and then lower one end into the ocean, with the other end out in space. How far will the water go up the big straw? <div class="Discussion_UserSignature"> <p><strong><font color="#ff0000">Vote </font><font color="#3366ff">Libertarian</font></strong></p> </div>
