Skill Level 2: Previous Rocket Experience Sug-
gested
A fun science project is to test various fin shapes
on a rocket to find out which one is best. The key to
any good experiment is to limit the variables so that
just one item affects the outcome. In this kit, we've
designed the rocket so that the rocket stays the same
and only the fin shape changes. We further isolated the
shape of the fin by making sure that the surface area
is identical from one shape to the next, and that the fin
span (how far it sticks out into the air) is also the same.
In this kit, there are four pre-cut fin shapes you can
test, and another eleven patterns that you can choose
from to make your own hand-cut fins.
To change out the fins, you simply slide the fin unit
off the rocket and slide on a new one. The shapes can
be swapped out in just a few seconds!

Make sure the tabs on the cross pieces protrude through the side plates. Apply a bead of wood glue over the tabs on both sides of the tool.

Slide the fin alignment fixture onto one of the 4 inch (101mm) long body tubes. Test one set of fins into the fixture. Position the bottom edge of the fins on one edge of the tube.
