This Instructable also outlines how to make a high-performing
rocket, which is just as important as having a great launcher.
The students in my engineering class have made rockets that can
fly over 100 yards from this launcher - it's rather mind-blowing
to witness. The video doesn't quite capture the sheer distance
that these rockets can reach, but I think you'll get the jist of
it. Step 2: Make the rocket It's easy to build a rocket that can
reach a distance of 50 feet. However, making an ultra-high-
performing rocket is actually quite challenging because all
aspects need to be designed to near perfection. At high speeds,
tiny imperfections are quickly blown out of proportion because
the forces acting upon the rocket are intensified. For example,
a nosecone that leans slightly to one side may not significantly
influence the rocket's performance at 40psi, however at 60psi
that nosecone may create an imbalance of friction created by the
air rushing by, causing the rocket to turn sharply and tumble to
the ground
