Combine these 3 substances in the following proportions by weight:
|
||
|
|
|
||
|
|
Potassium Nitrate.......63%
|
||
|
|
Sugar...................27%
|
||
|
|
Sulfur..................10%
|
||
|
|
(you can by this stuff at the drug store)
|

|

|
Note: use a diet scale or a gun reloading scale to measure the ingredients

What to do with the chemicals
|
||
|
|
-----------------------------
|
||
|
|
Put the 3 combined chemicals into a plastic refrigerator container with a very
|
||
|
|
tight lid (use a soft margarine container). Now be sure that the lid is on
|
||
|
|
TIGHT. Shake the container for about three minutes. You just made the rocket
|
||
|
|
propellant! This should be a yellowish powder...

Making the Casing(s)
|
||
|
|
-------------------
|
||
|
|
Items needed:
|
||
|
|
2 inch wide gummed, brown paper packaging tape
|
||
|
|
Scotch tape
|
||
|
|
1 foot length of 1/4 inch diameter hardwood dowel
|
||
|
|
single edged razor blade
|
||
|
|
wet sponge
|
||
|
|
|
||
|
|
Cover the hardwood dowel with several strips of Scotch tape (layed lengthwise
|
||
|
|
onto the dowel). Now cut a strip of gummed paper packaging tape (8 in. long)
|
||
|
|
and lay it, gummed side DOWN, on a flat surface. Dampen all but the last inch
|
||
|
|
of the back of the tape with a wet sponge. Turn the tape over and start at the
|
||
|
|
dampened end, start rolling it up around the Scotch-tape-covered dowel. After
|
||
|
|
having one layer of tape around the dowel, moisten the GUMMED side of the rest
|
||
|
|
of the tape and roll it up around the dowel as tightly as possible.
|
||
|
|
|
||
|
|
Problem(s):
|
||
|
|
|
||
|
|
Many times the paper tape will start to run off to one side or the other. You
|
||
|
|
can correct it like this (example-run off to the LEFT):
|
||
|
|
|
||
|
|
Use a single edged razor blade to the unrolled portion of the tape right next
|
||
|
|
to the roll. Start the slit at the LEFT edge of the tape and cut across the
|
||
|
|
tape to within 1/4/ of an inch of the RIGHT edge. Once the tape has been
|
||
|
|
partially cut, pull it to the RIGHT and correct the mistake. (Or vice-versa)
|
||
|
|
|
||
|
|
LAST STEP IN MAKING THE CASING: when done rolling a casing, hold the last edge
|
||
|
|
of the tape against a flat surface for a few moments; then slide the casing off
|
||
|
|
the dowel and ALLOW IT TO DRY...you can also bake the casing(s) in your kitchen
|
||
|
|
oven at 160 degrees (F) for about 30 minutes...

Making the Nozzles
|
||
|
|
------------------
|
||
|
|
Items needed:
|
||
|
|
Durham's Rock Hard Water Putty
|
||
|
|
Epoxy Glue (part A and part B)
|
||
|
|
'Six Penny' (3/32") Ungalvanized finishing nails
|
||
|
|
(quantity: amount of casings made)
|
||
|
|
one length of 1/4 inch diameter hardwood dowel
|
||
|
|
a 7/64 inch diameter drill bit
|
||
|
|
a 1/8 inch diameter drill bit
|
||
|
|
|
||
|
|
'Six Penny' finishing nails are about 3/32 inch in diameter. You will now make
|
||
|
|
the core of your rocket(s). Instead of using finishing nails you may use piano
|
||
|
|
wire that have the same diameter. You must pack the propellant down around the
|
||
|
|
finishing nails or piano wire., then removing it when you're finished.
|
||
|
|
|
||
|
|
Problem(s):
|
||
|
|
The finishing nails have a little row of grooves right near the head. This
|
||
|
|
will cause problems as you pull the finished rockets of the nail, so piano
|
||
|
|
wire is prefered.
|
||
|
|
|
||
|
|
The nozzle is made of the putty. To one you are first going to form a little
|
||
|
|
1/4 inch long plug of putty in one end of each casing. You MUST only form a
|
||
|
|
1/4 inch long plug of putty otherwise...
|
||
|
|
|
||
|
|
We are now going to tell you how to make a gauge (in case you use too much
|
||
|
|
putty or too little than required). Cut off a six inch length of the 1/4 inch
|
||
|
|
hardwood dowel that you bought to use the casing with. Wrap about a dozen
|
||
|
|
layers of masking tape around it so that one edge of the masking tape is
|
||
|
|
EXACTLY 1-3/4 inches from one end of the dowel. Slide a casing over the dowel
|
||
|
|
and run the end of it up against this edge of the tape. If you look in the
|
||
|
|
open end of the casing, you will see
|
