Alternately: Just Hold up a sheet and bang on pots and pans to make a mechanical noise

SCIENTIST: I, __ Einstein, after many years of intense research and development, have finally created my masterpiece: an enlarging machine! (Unveils machine with a flourish.). With this device, what goes in here (Gestures) comes out here (Gestures) twice its size.
FIRST PASSERBY: What’s this?
SCIENTIST: An enlarging machine.
FIRST PASSERBY: What does it do?
SCIENTIST: Well, you put something in here, and it comes out here greatly enlarged.
FIRST PASSERBY: Can I try it? MAD SCIENTIST: Sure, but be careful.
FIRST PASSERBY: (Picks up small stick on the floor, tosses it into churt. Small pause. Boy inside uses noisemakers and shakes box, pauses, then pushes big stick out the top chute.) Wow!! (Walks away amazed.)
SECOND, THIRD, FOURTH PASSERBYS USE A SIMILAR SCENARIO WITH WHISK BROOM, CHICKEN MCNUGGET, SMALL BALL.
OBNOXIOUS KID: (Approaches, throwing pebbles at box.)
SCIENTIST: Hey you, quit that! KID: (Continues throwing small pebbles, and drops one into the chute. Machine makes noise, then sends out fake rock which knocks kid on the head. He falls over unconscious. Other scouts drag him off.)
SCOUTMASTER AS BUSINESSMAN: (Walking hurriedly, checking his watch. Stops and stares at box, and says sarcastically)What’s this thing!?
SCIENTIST: (SAME SPIEL AS BEFORE) BUSINESSMAN: Yeah, right! Who are you trying to kid? Do you have a license for this? This is a piece of junk!! It belongs in the dump! In fact, here’s what I think of your great invention! (Turns back to audience, makes spitting noise into chute. Machine starts up, pauses. He looks into top chute. Scout in box throws a cup of water on his head. He stalks off angrily.)
LITTLE GIRL (BOY IN COSTUME): (Skips up to box) What ya got there?
SCIENTIST: It’s my invention, don’t touch it!! LITTLE GIRL: (Touching machine) What’s it do?
SCIENTIST: Stop it! It enlarges things, now leave me alone!
LITTLE GIRL:(Sticks out tongue, then tosses baby doll into machine. Machine starts.)
SCIENTIST: (Panicked) What have you done!? Oh my, oh my! (Machine pauses)
BABY IN MACHINE: (Comes out of back, stands up, spies scientist, and begins chasing him around the room.) Mama! Mama! Mama!
One of the tarp holders says “Come one, come all; see the new, incredible enlarging machine! Throw anything into it and see the item returned at twice its normal size!” Several people walk up and throw in the smaller items, catching the “enlarged” items as they are passed back over the tarp. One person walks by, saying “I don’t believe this machine actually enlarges anything!”
So saying, they spit on the tarp. The person behind the tarp then upends the bucket of water on the unbeliever’s head!
