Lupatnieks Posted January 21 Posted January 21 Hello, I was wondering if in stead of melting r-candy you can moist it with alcohol while pressing into the rocket. Similar as you do with BP before you granulate it. This would make the sugar and kno3 bond together and more dense and easier to compress into the rocket(?) Or am I thinking wrong here?
Darkonez Posted January 22 Posted January 22 I’m no expert but when the ingredients are melted I believe they would mix much better to a molecular level? And something setting after heating is a lot different to something drying! I imagine water in the rocket tube could compromise the casing if made of cardboard/paper annd take a while to dry fully and if it’s some kind of plastic the drying would take forever? no pro here, more a half educated guess.

The requirement of water is more for granulation of BP as compared to the requirement of water needed to dampen for your purpose. Use small amount of water or water/alcohol mixture so that the composition only clumps. And when pressed it again comes into dust form. It will not affect your cardboard casing, if kept in Sunlight immediately for drying.
FrankRizzo Posted January 23 Posted January 23 It's probably not ideal, even with denatured alcohol that's 99%. The problem that you'll run into is that sugar is fairly hygroscopic and will hold onto that 1% moisture after the alcohol evaporates. The moisture will slow down the fuel and make it unsuitable. Acetone might work better, but you'll need to use a fresh can or add some oven-dried Epsom salts to dry it.
