Step 5: Pour the litter
Put about 1/4 inch of kitty litter into the tube being sure to press tightly against the working surface so not to spill any out.
Then,put the pencil in after to litter
Starting slowly, pound the pencil into the tube compressing the kitty litter

- The reason Kitty Litter is used is because it is almost 100% Bentonite clay which is the same thing used in model rockets (the sealant)
Step 6: Add the Black Powder
Follow the Litter with the Black Powder being sure to compact it thoroughly.
Step 7: MakeYour Nossel
Taking the hammer and nail .....or better yet a drill bit in a drill.... CAREFULLY tap the nail into the top layer of litter all the way through to the black powder(this is the nossel)
Ps the smaller the hole, the more propulsion. But with a better chance of it exploding on ignnition

This grinding process can be dangerous.
If the KNO3 is dry it can ignite while grinding with a surprising flash and a lot of heat. So always wear gloves, safety glasses, and safety clothing.
Back in 1947 when I was a child,between 8-11, in NYC I made rockets using a modified black powder recepe. The fuses were made with cotton string soaked in KNO3 dissolved in water at room temperature and then the fuse cord was rolled in finely divided magnesium and sulfer and air dried. The fuses worked but were not very reliable time wise, between 15 and 60 sec/inch. Never bothered to fine tune the fuses as I was more interested in flying rockets and testing rocket fuel.
P.S were do u get saltpeter (potassium nitrate)
In the UK you can only buy it online. When I got some I bought it from a website called "HobbyChemicals" it costs £9.99 for 2 Kg.
If your in the US then you can get it in big tubs of stump remover which is usually like 99% KNO3 so thats good enough. I don't know about other countries though :P
P.S there's also a version of the website for America :)
