5. Inverted Bottle Challenge
This classic trick actually has two solutions. Set it up by placing a bill flat on a bar table and standing an inverted beer bottle on it. Challenge anyone to remove it without touching the bottle or knocking it over. Ninety-nine point nine percent of people will try the old “tablecloth” move of ripping out the bill as quickly as possible. And 100% of them will fail.
You can show them how it’s done by a) slowly rolling up the bill until it gently frees itself from under the bottle, or b) by lightly banging the table with the fist of one hand while gradually sliding out the bill with the other.

Place an olive (or cherry tomato, or similar object) on a coaster next to an empty Martini glass, with an empty wine glass standing by. With a twinkle in your eye, and mischief in your heart, tell a friend you can move the olive to the glass without touching coaster, olive, or martini glass. Then place the wine glass over the olive and start deftly circling it, generating enough centrifugal force to lift it and make the transfer.
Promise you can talk for one minute without using a word with the letter ‘a’ in it.
Count from 1 to 100, which takes about a minute. None of the numbers you’ll say contain the letter ‘a.’
