I've been making "rocket candy" engines for over a year now as a cheaper alternative to commercially made motors. I heat it up on the stove until the sugar caramelizes and fuses with the KNO3 then put it in a PVC pipe case see attached picture. For the PVC casing, I use gorilla glue to bond the parts together, and I haven't had a problem with that specific casing after four separate test firings. Granted, I've gone through 4 of them using different designs, but I've done about 30 test firings trying to get it working right. I put a steel washer inside the cap to act as a nozzle, otherwise it just melts the plastic.

I put a steel washer inside the cap to act as a nozzle, otherwise it just melts the plastic. The biggest issues I've had with the PVC pipe is the casing bursting after several test firings from general wear and tear, but it normally just pops apart and doesn't cause any damage to the test stand I built or anything around it.
I briefly used a similar looking steel casing, but it launched the test stand after the third test and violates NAR guidelines. Based on comparing the wear after each test fire, the steel casing would last a lot longer than the plastic casing. However, it cost about twenty dollars for the steel case compared to for the PVC casing. I would recommend using the mix to start off with and a PVC casing. It's cheap in case it messes up and shouldn't hurt anything if you take proper safety procedures don't stand right beside it.
Remember what happened to Jack Parsons. Rocket Science and kch like this. You seem intent on pursuing this. I found this book helpful when I tried it out. I did it, it worked, I'm alive. It had reasonably good techniques for making the nozzle, igniter, coring, etc.
Not much included on designing the rocket aerodynamic stability or the avionics bay to eject a parachute. Do not launch without a parachute. Your rocket is then an artillery round. I also was extra careful in heating the fuel mixture. The jacketed heating was very even, and that reduced the chance of autoignition. The mixture will auto ignite at about 20 degrees F above the target temperature to pour.
I'd never trust a stove top with that. I also used about. The fuel also adhered better to the PVC casing if you did a quick "priming" of the PVC with solvent right before pouring the fuel in. Keep your solvents far away from your heat source for the fuel mixing. Ground everything. Have an escape route. IF it catches on fire, you will not be able to put it out. It burns hot enough to melt any metal container you put it into.
As for introducing liquid hydrocarbons You are building a solid rocket motor, not a liquid fuel. They are completely different in the combustion. You will have a bad luck day if you try this. Besides, look at your chemical balance of fuel to oxidizer if you used potassium nitrate.
If you can walk back your urge to play garage chemistry, go get started properly on rocket design, and then buy safe commercial high power rockets. For your "illumination" All reactions are constrained by achieving the optimum stoichiometric ratios Add me to the ranks of people saying that this is a fantastic way to kill or maim yourself.
Just don't. Try Here. Very Informative! Don't forget a generous dose of caution and common sense. Keep us posted You will find your biggest challenge and the greatest performance increase can be had from the chamber and nozzle design. There is a vast amount that can be done without experimenting with additives.
If you want max performance get the structural mass as low as possible to give you best mass ratio. SMF 2.
Also, I need a way to track it… I plan to attach the booster to rocket by a tight fitting piping so I can take the pencil out and put a new one in the case it breaks during landing, the issue of tracking it is still being thought up on Hope this get replies!

Use of this video content is at your own risk. Using some kitchen chemistry and a few common household items, I tested a few different methods for DIY rocket fuel. This is because the sugar caramelizes and absorbs the KNO3.
The smell is similar to that of making candy, and that's why this is sometimes referred to as "Rocket Candy" or "R-Candy". When it's runny enough, it can be poured into a casing to cool down and solidify. Watch out, it's hot! I made another batch and packed it into a homemade rocket motor casing that had a nozzle made from kitty litter.
I was impressed to see it actually worked! I think this rocket shot up a couple thousand feet. If you missed the video at the beginning of the article, scroll up or watch it directly on YouTube! If you liked this project, perhaps you'll like some of my others. Check them out at thekingofrandom.
Just wondering, what kind of output do you get out of this? As in, how much could this stuff lift. Thompson ur cool I like u I saw ur many vedios I got impressed and subscribed can u now only give me a idea of making a project for my science Edex iam in 7th grade can u pls do it 4 me.
