Welcome to the Straight Dope, @psmith3 . While we don’t have a rule here against bumping old threads, it doesn’t really serve any purpose to bump two old threads on the same topic (this one and Magic: Making big things disappear). In fact, it can make things confusing, if people reply in both, and it’s hard to keep track of which thread is which. Accordingly, I’ve deleted your post in the other thread, so we can discuss the question here.
