This game can be used in small groups of any age or level, and is a good way to get people to do some self-itroduction. Get a timer and conceal it in something that you can pass around, but so that you can still hear when the alarm goes off. Set the timer to some random amount of time, put it inside the bomb, and start passing it around. Whenever it goes off, the person holding it has to say one sentence about themselves. To make it more challenging, you can make it so that the first time someone blows up, they have to say one thing, but the second they have to say two things, the third they have to say three things, and so on. With kids it helps to have a rule saying that if the bomb falls to the floor, both people near it have to say something, or come up with some sort of other punishment.
