From Quirkology's Richard Wiseman comes another roundup of pub tricks that you can use to impress and/or vex your friends.

As with Wiseman's previous tricks, a lot of these are actually pretty clever (bet #2, for instance, relies on the creation of a partial vacuum, and bet #4 on an implementation of Bernoulli's principle), while others – # 10, for example – could get you punched in the mouth, if you don't choose your audience wisely. As always, you'll want to roll these out at your own discretion.
