this was just a test: new mix, new tooling, new fuse etc plus it's fun to witness the power of rocetry without craning your neck!

heh actually it's a long sheet of paper rolled into a thick walled tube since i'm too cheap to buy cardboard tubes.

dude, What was the propellant? I want to know

in the immortal words of Prof. Jagger: "you can't always get what you want" if you search around for rocket propellants though you'll find more than enough info a safer (slightly anyway) starting point: try searching for "James Yawn"

Kaelessin (author) in reply to bylerfamilyNov 20, 2008. 6:20 PM

bentonite (aka kitty litter)

(this isnt really an instructable) Is this core-burning? If so, you might try end burning. Try a larger nozzle orifice. Try slower fuel.

i've since fixed the issue . . .i had a 4mm nozzle and upped it to 5mm and now it works like a dream. I've also switched to the KN03/Sugar version since it's easier(and significantly safer) to make and also cheaper. (btw: i realize that this is not an instructable which is why i posted it as a video and not as an instructable. Thanks for the concern tho)

im no rocket scientist, but my guess it would work a heck of a lot better if you had the thrust pointing down instead of up.

Kaelessin (author) in reply to thematthatterMay 29, 2008. 8:25 AM

lol yes you're completely right but this was a test only and I didn't want a potential fireball flying through the neighborhood so I "anchored" it with the nozzle up. looking back and seeing how my nozzle blew out i probably wouldn't have had an issue of it going too far but best to be on the safe side eh?

Kaelessin (author) says: May 28, 2008. 10:25 PM

I won't say what it is exactly since i didn't actually make it completely from scratch and I don't want to be an advertiser but if you must know I can hint . . .it's a derivative of black powder(this is actually grey though)
