Think of this as the 3 Stooges building a rocket ship. It is pantomime only.  With all the slapstick bumping, shoving, and horseplay possible.

Cast:     3 boys as astronauts in white suits and helmets  1 Cub in uniform
Props:  3 five-gallon popcorn cans or something similar painted white or covered with paper.  These are numbered 1,2,3.  Stage 3 needs 3 fins.  A nose cone made from poster board.
Action: Boys stack stages of rocket and nose cone in varying sequences always wrong.  Numbers could be upside down. Suggested are:

I.                 1/ 3/NC/2
II.                2/3/1/NC
III.               3/1/2/ NC                               
IV.               2/1/NC/3
V.                2/NC/3

Finally a small Cub Scout comes out and shows them how to assemble the rocket.
