1 glass, a matchbook, six coins, and an ashtray with water.

 

Bet your friends one drink that you can get the water out of the

ashtray using only the ingredients mentioned and without moving

or tilting the ashtray.

Make sure ashtray is filled with at most a quarter inch of water.

Stack the coins in the centre of the ashtray so the top two coins

are above the water.

 

Place four unlit matches on top of the coins.

Light the matches and immediately cover the flame and coins

with the glass. The water will be drawn into the glass. Collect

your bets.
