Pass the Bomb

For approximately thirty nail-biting minutes, player's nerves are tested by the threat of the ticking bomb!
A card is drawn bearing two or more letters. The bomb (variable time fuse of 10sec-1min) is 'lit' and is passed to the first player. In turn players must shout out a word that contains the letters on the card and pass on the bomb before it goes off.
For any number of players, but be warned- not for the shy and retiring!
For any number of players, ages 12+
