Your task is to build a fuselage.
You will need:
1. A
paper towel tube (many kinds work, like a Reynold’s
Wrap tube, etc.) but it must be the general length of a standard size paper
towel tube. (In other words, don’t use a Christmas Wrap tube, or don’t cut one
for use in this project – they are too flimsy!)
2. One
half of a plastic Easter Egg, that will fit rather perfectly on the top of the
tube.
(You decide which end of the tube
is the top or bottom!) The egg-half
needs to fit snuggly, but don’t force in onto the tube. The tube is useless, if
the egg causes the cardboard of the tube to cringe or be bent in any way. It is
sometimes difficult to find an egg-half
that will serve this purpose, so be patient in your ‘hunt’.
3. You
need about a square foot’s worth of stout cardboard material. The firmness of
an old 33 RPM record is good. You might not find one of those, but use that as
a gauge for the thickness you use.
4. Great
scissors or a single-edge razor – the single-edge razor is best for the precise
cuts you will need to make.
5. A
ruler, Hot glue gun & glue.
Directions.
1. Draw
three congruent quadrangles
similar to the one below on the cardboard material. However, be sure that side “A” on YOUR
quadrangles is between 3 an 4 inches in length!
2. Carefully
cut out these quadrangles. They are now your rocket’s fins.
3. Find
a way to accurately measure the
distance AROUND your paper tube, and make three marks of equal distance on the
tube near the bottom.
4. Use
these marks as guides to make a 4” bead of hot glue on the tube on which to
glue your
fins. Be sure to hold them perfectly straight up
and down as the glue dries. This takes about one minute. (Glue ONE at a time, and to help keep them
straight as the glue dries, look through the tube as you hold the fin to the
glue, this will help you see if the fin is leaning to one side or not.)
NOTE – when you glue
the fins on, let about ½ of the fin hang BELOW the bottom of the tube.
This gives your rocket far better stability, and something to “stand” on when
you’ve glued all three on.
5. Glue
the short piece of straw straight up and down the rocket, and between any two
fins of your choice. The bottom of the straw should be flush with the bottom of
the paper towel tube (now called the “fuselage”!)
6. Paint
or color your team’s rocket, but be aware that any out-of-balance enhancements
can seriously affect flight, and postpone lift-off. Be perfectly symmetrical with everything you do!
