This text file was written on an Apple ][e with 192K and in 80-col. August 8,
|
|
1986 9:00 PM (pacific). Be sure that you have read the file 'How to Make Sugar
|
|
Rockets' before reading this file. This file is actually Part II of that
|
|
File....

Time Delays & Special Effects
|
|
-----------------------------
|
|
In order to provide room for time delays (et cetera), you will need a longer
|
|
rocket casing. So go out to the store again and buy wider brown packaging tape
|
|
(3 in. instead of 2 in.). But the thing is that this type of tape is not sold
|
|
in most stores, so go look in a phone book for large paper suppliers that sell
|
|
packaging supplies. To make a rocket casing with a time delay, you just have
|
|
to follow the instructions in Part I (How to Make Sugar Rockets) except (there
|
|
are some changes):
|
|
|
|
1> Use the 3 in. packaging tape to make a 3 in. casing.
|
|
2> When loading the propellant, instead of stopping at the top of the mandrel,
|
|
continue working, using the flat, undrilled end of the tamp, and pack an
|
|
extra 1/2 inch of propellant in on top of the mandrel.
|
|
3> You will need to form a tiny hole through the epoxy glue plug, to do this,
|
|
(after packing the propellant) stick a large sewing needle into the
|
|
propellant right at the edge of the rocket casing, you then press it into
|
|
the delay powder to a depth of 1/8 of an inch, now firmly pack in your wad
|
|
of tissue paper or paper towel and then pour in the front plug of epoxy.
|
|
4> After the glue dries and hardens, use a pair of small pliers to twist and
|
|
pull the needle out of the epoxy, leaving a tiny pin-hole through the plug.
|
|
|
|
Now you're all ready to go...
|
|
|
|
|
|
Making a 'Pop' sound and smoke
|
|
------------------------------
|
|
To make a 'pop' and some smoke at the end of the rocket's flight is easy.
|
|
All you have to do is fill up the pin hole with black powder or Pyrodex powder
|
|
and add another 1/19 of a gram (1/2 as much as you used to prime the rocket).
|
|
Press in a another wad of tissue paper (or towel) and pour another epoxy cap on
|
|
top of that. When the falme inside the rocket reaches the front of the time
|
|
delay powder, it will flash through the pin hole and ignite the powder. This
|
|
is how to make a fire cracker like 'pop' and a puff of smoke at the end of its
|
|
flight. Making the flames a certain color is also desirable. Well, it is very
|
|
simple. If you want a green flame when it is lauched, this is what you do:
|
|
|
|
Go out and buy some Copper Sulfate (powder). Then you glue the powder on
|
|
to the rocket casing(s) at the ends all the way around. Use Elmer's glue to
|
|
do this. And that's it! When the rocket is ignited, it will be launched as
|
|
the Copper Sulfate burns (Elmer's glue melts), causing green flames. You may
|
|
use other chemicals to produce different colors. But be sure to use the slow
|
|
lift-off option that was explained in the Part I (so that you can observe it).
|
|
|
|
|
|
Making a Nose Cone for better Performance
|
|
-----------------------------------------
|
|
To make your rocket(s) fly better, you will need to make a nose cone. Make
|
|
something like a witch's hat out of paper and masking tape and glue it onto
|
|
the nose of each rocket. This should not require any assistance (I assume
|
|
that you must know how to make a nose cone. It shaped like a funnel.)
|
|
|
|
|
|
Using the Time Delay to Pop a Parachute
|
|
---------------------------------------
|
|
To pop a parachute, fill the pin hole with black powder and add a very SMALL
|
|
amount of powder on top of this. Then cut a disk of stiff paper from a
|
|
3 x 5 inch file card about 3/8 of an inch in diameter, and using on end of
|
|
your powder tamp, press the paper disk into the nose of the rocket on top of
|
|
the loose powder (be sure that you have not made a nose cone and have glued
|
|
it onto the rocket).
|
|
|
|
|
|
Second Stage Rocket
|
|
-------------------
|
|
If you want to have your rocket ignite a second stage, then use a single edged
|
|
razor blade to cut the excess length of the cassing off right at front of the
|
|
front plug. Then fill the pin-hole with loose powder and cap the FRONT of the
|
|
rocket with the powder ppaste just as you did to the back end when priming it
|
|
for firing. Make sure the front of the rocket is marked, once te ends are
|
|
capped, you won't be able to tell which end is which. When igniting a second
|
|
stage, place the priming cap of the second stage engine in contact with the
|
|
front end cap or first stage motor. When the flame in the first stage motor
|
|
reaches the front of the time delay powder, it will ignite the cap at its
|
|
front, which in turn will light the priming cap of the second stage engine.
|
|
|
|
|
|
Making a Second Stage Stick Rocket
|
|
----------------------------------
|
|
When you make a second stage stick rocket, you will need a longer stick to
|
|
balance the extra weight and you will have to connect the two stages so that
|
|
the second stage can slide easily away from the first after the first is spent.
|
|
Wrap a single layer of paper tape around the fron of the booster engine (first
|
|
stage motor), so that the tape is glued to the front of the booster but sticks
|
|
1/2 an inch out in from of the finished, capped engine. After the glue dries,
|
|
you can slide the tail of the second stage into this paper sleeve off the first
|
|
until the priming cap of the second stage mmotor touches the front cap of the
|
|
first. Glue or tape the longer guide stick to the second stage engine, leaving
|
|
the first stage engine and its paper sleeve free. (Note: This two stage stick
|
|
rocket is 2 rocket casings connected to a longer stick. This is an easier
|
|
explaination.)
|
|

|
Substitutions & Misc.
|
|
---------------------
|
|
You can mix white baking flour with epoxy glue if you cannot get the water
|
|
putty. Instead of getting flowers of sulfur, you can get dusting sulfur at
|
|
a nursery or fertilizer supplier. Dusting sulfur will result in a better
|
|
rocket. Never put the 3 chemicals (sulfur, saltpetre, and sugar) in a blender,
|
|
if you do, you'll get a real big kick out of it...
|
|
|
|
Well, good luck and look out for more files in the future...
