"1 lb." KNO3 Rocket

This rocket was a throw together of some propellant I messed up...

I was making a batch of 63:27:10 KNO3\Sugar\Sulfur propellant, but for some reason I put 12.6 grams of Sugar, 5.4 grams of KNO3, and 2 grams of Sulfur... I ended up adding some more KNO3 and sulfur without measuring so I just tweaked it until it worked decently...

The rocket would have actually taken off well if the core was a sufficient length and the propellant was made correctly...

This is launched in a neighbors yard with a fireman and plumber by my side :)

Small flash header if you couldn't tell...

just interseted did u melt the mixture or just stuffed it

[frogy1752]

Consolidated (rammed) dry. Just a rough mix at that, the KNO3 and sulfur are pretty coarse.

Haha why do you have a plumber by your side ... LOOOL!

[frogy1752]

In case the toilet gets clogged.

haha. just kidding though, he lives near.

thats not 1lb. that size, about 120g.

[frogy1752]

That's not how the motors are rated.

"1 pound" refers to a 3/4" diameter rocket. In which a lead ball that has diameter of 3/4" weighs about 1 pound.

grind your kitty liter into a fine powder, it doesent matter if your fuel mix is dry or cooked just keep the mix from drawing mosture or it will cato tape the ends with masking tape to keep it dry, plus ive found any pvc tube over 1/2 inch tending to cato reason why is the extra burn time tends to melt the tube.!! line with card board then pack your fuel..! i catoed 9 engine's to prove this point,

@hellkid94 Burham's rock hard putty, its hard to work with but holds up realey well..! let dry for two days once dry put tape on the end to prevent mosture from softening the putty, happy rocketing

@hellkid94

Kitty litter is just a cheap way of getting ahold of Bentonite Clay. try crushing Fresh Step (recommended to me as being good for nozzles) into a very fine powder, it works surprisingly well, if that's not strong enough then you can order pure Bentonite clay from a variety of places including skylighter. I'm working on a better grade rocket nozzle mix described by someone on skylighter using bentonite clay, grog ceramic clay and paraffin wax.

hey instead of the cat litter, is there an alternative?(plz reply)

[DoctorTerrorist]

it may have messed up cuz the S made it to reactive

[TheBombBros]

nice motor!

i always tell people they dont need a long stick to keep it stable.

you seem to already know that! its been a while since i made sugar motors,

whistle motors are more for me. but thanx for the upload. good vid.

[Thechessdragn]

He did designate the one pound in quotations, indicating that what he built is called a one pound rocket although it does not weigh one pound.

[disturbedone5009]

Yeah were so crazy when we can't see clearly that weight is a measurement for diameter. I mean we must be stupid for not knowing that.

[ghostom998]

how dya make the flash head?

[SykonoT]

mines better
