(This skit is best set up in the opening of the campfire circle so that no one can see what is happening "backstage".)
Props: A blanket (or on stage a large piece of cardboard on which is drawn a machine, with a flap in the front), a teaspoon and a ladle, a tin mug, and a pot.
(Two boys hold up the blanket behind which is the largest boy, who is also the machine operator.)
Circus Barker: Alright, step right up and see the world's only enlarging machine! For one small dime, one-tenth of a dollar, you can try the world's eighth wonder.
First Boy: [shows everybody his teaspoon] I'll try it, mister. [puts imaginary dime into a pocket of a boy holding the blanket and cranks his arm]
Operator: [clanking, whirring sounds, throws ladle out]
Barker: There you are, folks, one tiny spoon in, one big spoon out! Who's next?
Second Boy: [shows tin mug] Me, mister. I'll try it. [puts in an imaginary dime, cranks arm]
Operator: [clanking, whirring sounds, throws pot out]
Barker: Isn't that the marvel of the world. One tiny mug in, one big mug out. Step right up now. Who's next?
Third Boy: [runs up, puts in dime, cranks arm, and jumps in]
Operator: [clanking, whirring sounds, and jumps out] (We discourage the ending where the actor spits into the machine, receiving a mug of water in the face.)
