Launcher
You can get these parts from
Home Depot for less than $5.
- 3-foot long ½” PVC pipe.
- ½” Right Angle PVC pipe coupling
- Block of wood 10”x 4”x 1”
- Two 1” sheet rock screws.
- One ½” pipe hanger
- 2-liter soda bottle.
The wood block helps keep the
launcher stable.
(Even thought it ‘s called ½” PVC
pipe, it is actually 5/8” on the
inside and 7/8” on the outside
diameters.)

Launcher
Cut two 1-foot long pipe sections.
If you get the PVC pipe from
Home Depot, you can usually cut
the pipe sections there with a
hack saw or pipe cutter. If not
you will need a hack saw.
Connect the PVC pipes and the
soda bottle.

Fuselage
11”
½” PVC pipe
You can use thin card stock or 22lb
weight paper (typical printer paper.)
Roll an 8.5” x 11” paper around a ½”
PVC pipe. Tape this paper to the
pipe. Use small 1” sections of tape.
It is easier to control small tape
pieces.
Then wrap a second paper around
the paper that is taped. This will
make your rocket fuselage have
minimum friction with the pipe when
it takes off.
Tape the second rolled paper and
slip it off the pipe.

Fuselage
Flatten and cut a point on one end.
Tape that end so it makes an air
tight tube when you blow in the
open end.

Nose Cone
6”
4”
3”
Wrap a 6” x 4” piece of Foamie
into a cone.
Hot glue or tape the cone shape.
Cut the open end of the cone so it
is round.

Nose Cone + Fuselage
Hot glue the nose cone
to the fuselage.

Tail Fins Simple
11”
Start with a 8.5” x 11” card stock
or 22lb paper.
8.5”
Fold in half,
Hamburger style.
Cut at the fold.
Bend in half and
cut at the fold.
Fold the two
strips in the
middle and cut
at the fold.

Mark a
straight line
from corner to
corner. Put
the two pieces
exactly on top
of each other.
Tail Fins Simple
Cut along the
diagonal line
and you will
have 4
symmetrical
fins.
You need to make flanges on each
fin so you can tape or hot glue
them to your rocket fuselage.
Score and fold
a flange about
¼” along the
long edge of
the triangle.
Then cut a
small slit from
the edge to
the fold.
Bend the top
flange to the
left and the
bottom flange
to the right.
You need to do
this for all 4
fins.

Tail Fins Rugged
11”
8.5”
Fold in half.
Hamburger
style
Build these fins instead of the
simple fins if you want really
rugged fins.
Cut the two halves
www.Build-It-Yourself.com
Fold the two
halves in the
middle.
Tail Fins Rugged
The goal is to make 4 fins that are exactly symmetrical!
Cut the two
folded
halves in the
middle.
Fold the two
halves in the
middle.
Cut the four
rectangles into
four equal
triangles.

Tail Fins Rugged
The goal is to make 4 fins that are exactly symmetrical!
Cut the four
fins along the
dotted line.
Now you need
to fold flanges
so you can glue
or tape the
fins to the
fuselage.

Nose Cone + Fuselage + Fins
Hot glue the fins
to the fuselage.

If you want your rocket to fly straight you will
need to mount your fins at right angles. You
can make a cross hair template to ensure good
alignment.
Try mounting your fins so they will make your
rocket spin. Your rocket may not go quite as
high but it may travel in a straighter line if it
is spinning like a bullet.

Nose Cone + Fuselage + Wings + Tail
You could add wings and a tail instead of fins
and launch a glider. Before you launch it,
make sure it glides well. You can position the
wings forward or backward to control the
center of gravity. You could also cut
elevators to control loops.
You can stiffen the wings by folding the
leading edge or taping a coffee stirrer stick
to the leading edge.
