The best home made rocket fuel ever!

[rstevewarmorycom]

Try just KNO3 and Sugar, better still, bring the sugar up to melt in

a double-boiler (water bath) and stir in KNO3 with a wooden spoon

(a metal spoon can set it off) and then cast it in a fuel grain in the

rocket tube with a channel down its center (leave a rod through the

mold you can pull out) and let it cool. Use about 3.5 parts to 1 KNO3

by weight.

@marinskater Duuuude, that's fuckin' awesome :) Happy ride and post the freakin' vid when u have it ready :|

[rachetomodele]

@marinskater Dude, U wanna go into space? :))

[yudiweb]

wattafak fire crackers, dude :)

[spacecadet35]

Needs more oxidiser. 

[tallolivier]

this isnt true this sucks and its bad for r candy

[ThePyrofuly]

it has a nice beginning bas as you might have noticed there is an un-productive flame for a long time after the initial flare, this is where all the excess elements are burned! id cut down at least half the sulfur and add add half a tablespoon extra potassium nitrate. Happy pyrotechnics

[tamkakit1233]

Why add water?

[jmar1371]

Putting R-candy in a steel pipe is NOT a good idea.

[randyrox69]

mines bettter :)

[robotandlegolover]

i have a lighter, not a blow torch, that is like a blow torch! its an awesome lighter, fueled by buthane and refillable

[Jess887cp]

nice lighter you've got there. :)

[TheSkaterGuitar]

@david1513 why? why do people cook it then?

[TheSkaterGuitar]

@david1513 Hey thanks man! yeah I know about the water thing but I wont be adding any syrop in it neither

[ThePyrofuly]

@david1513 hey nice formula, water isn't bad for a formula just as long as it has all be evaporated before cooling, this ensures it is still dry, some formulas are easier with water and some it isn't necessary.

[christianthebom]

@david1513 i make r candy all the time and you don't need to let cure for that long so long as the cooed fuel is brittle and snaps when broken its fine and will produce plenty thrust

[antiswattt3]

@david1513 lol.

[Mitrolaja]

Adding sulfur into the KNO3 sugar propellant makes its Isp lower, because the sulfur doesnt burn well and the molecuar weight of the burn products are higher and it can't accelerate in the nozzle.

[Nukedeuce]

true, just use KNO3 sugar, corn syrup if you want, and mabey some baking soda or iron oxide =)

[mrblah125]

Oh baking soda has a similar effect to iron oxide??

[Nukedeuce]

@mrblah125 ya i believe so... not 100% sure tho.

[nicksynnz]

@mrblah125 Sodium biccarbonate should release CO2 and not act as a catalyst.

One would think the CO2 would dampen the reaction... Put on a vid of this please.

[randyrox69]

@Mitrolaja wrong suffer releases more gasses than kno3 thus leading the rocket to have more thrust

[jeabo0adhd]

It looks like it blew out its nozzle.

[5rowlew]

anyone have a good tip for pakin a wet rocket mix into the shell i allways seem to have airgaps

[johnarm64]

use cornsyrup

[Nukedeuce]

melt it

[tullgutten]

make a nozzle and drill a hole in to it :D

[Incredibleman007]

I didnt, Its not my video

[Incredibleman007]

Preaty good but you probably need more KNO3.

[filipzbroinski]

nice
