5 Cent Sugar Rockets

[cannon freak]

I was wondering if those small rocket engines that you can build out of some simple materials are legal or not, because I can not find any legal information on them in Canada.

Im not shure if this is against form rules, but if it is just delete it.
Also I do not plan on firing any of them out of a potato cannon or using them as bombs.

can you give us a link?

i have read about those before. yes i think they are legal because i saw a popular science article about making a rocket engine out of potassium nitrate and a milky way. i dont think they would publish how to do something illegal in a national magazine. dont hold me to it though.

The formula is
63 KNO3
27 Sugar
10 Sulfur

Grind the individual ingredients to a fine powder state and sift together well. This formula is extremely hygroscopic. So keep it in an air tight container when not in use.

You better use a ball mill.The engine will burn much faster if you make a little chanel trough it's length.

And also www.xinventions.com I have trouble with my rockets i ahev about a %60 rate of them working and the rest either explode or shoot out there end caps.

thanks rna_duelers
ps: im down in tassie, where are you?

EDIT: can i replace pottasium nitrate with an oxidiser of the same power?

[boilingleadbath]

Like what? NaNO3?
I wouldn't reccomend the above. It's more hydroscopic than KNO3, and will make your rockets get sticky even faster.

[Benny]

thats ok, i just found a 500 gram bag of pottasium nitrate.

Yeh im from NSW, and sodium nitrate is fine for use with rockets thats what i was using half of the time and i dont leave then for any period of time so they dont collect moisture i usualy make them in the day and fire them at night for the cool glow in the sky.
