Step 6: Make some rockets
There are basic building instructions on the rocket template. Decorate and cut out areas as directed.
Roll the rocket body section onto forming tube, with the bottom of rocket (where the fin placement lines are located) just above the tape at the end of the forming tube. This creates an open space at the top of the tube, where the cotton balls will go.
Tape the body tube together, but NOT to the forming tube. Fold the fins and tape them in place on the fin placement lines. Place two cotton balls into the open area at the top of the paper tube, and cover with a couple of pieces of tape. Remove rocket from forming tube.
