Hi everybody im that buddy king\_al mentioned in his last post. Here’s an illustration of what he ment to say in his last post. 😉

King Al suggests that if you fill his tube with air, so the pressure would be the same as the pressure at ground level, the pressure only would be a little different from the top of the tube to the bottom of the tube. He also believes that this pressure doesn’t need any help to be uphold. For this to be true you’ll have to ignore the influence of gravity! I suggest that that because of gravity the pressure will be the same as the pressure outside the tube.  
Now wht do you guys think?

Welcome to the SDMB, and thank you for posting your comment.  
Please include a link to Cecil’s column if it’s on the straight dope web site.  
To include a link, it can be as simple as including the web page location in your post (make sure there is a space **before** and **after** the text of the URL).

Cecil’s column can be found on-line at this link:  
[Can a cloud weigh as much as a 747? (13-Mar-1998)](http://www.straightdope.com/classics/a980313a.html)

I see you were intending to join an already existing discussion. The current discussion can be found here:  
[Cloud weight weasling.](http://boards.straightdope.com/sdmb/showthread.php?threadid=63264)

I would suggest continuing the conversation in that thread instead of starting a brand-new one (use “post reply” instead of “new thread”). To encourage you to do so, I’m going to close this thread.
