Step 7: 5. Attach Fins
5.1. Glue the base of one fin along an FL line at the bottom of the rocket. Make sure the fin is square to the surface of the rocket body and aligned with the FL line. Hold the fins in place for a few seconds until the glue can hold the fins in place.
5.2. Repeat 5.2 for each fin.
5.3. Set the rocket upside down on a flat surface or over a pole and allow the fins to dry.
