Dave The Gnome: good explanation! 'Course, maybe Blackcatter is going to do it with his WHISTLE!
Jimmyt: What did your mother tell you do with ANYTHING before you put it in your mouth?
Stu: The blutack thing's a new one on me and undoubtedly needs to be explained by someone who understands Boyle's Law, Charles' Law, Avagadro's Principle and Bernoulli's Principle. I can't imagine whistle manufacturers going that deeply into the science. I've read these theories then still watch in amazement as Jumbo Jets impossibly take to the sky. And it's always a surprise to me when a gas pump shuts itself off when my tank is full!
