Testing Different Potassium Nitrate and Sugar Mixtures 

Oh yeah!

Use ground up regular sugar. Powdered sugar often has some corn starch mixed with it.

@@cocospops9351 I used powdered sugar with corn starch and works really good.

@@sabik6979 yup it works alright

@@corrick4339 Correct

The ratio you said above works well for model rocket engines along with some pretty kick ass fountains if you add some aluminum or other alkali earth metal salts. Strontium and barium make some pretty cool colors.

@@Sam-ik6uj how much strontium and barium?

Very interesting.

It's good for making firecrackers, right?

@@TheRojo387 of course, it's a fuel mixed with an oxidizer

Hmm 3 years ago I wonder what your using that mixture for today hmm not making slugs I hope

Gamma Relay fourth*

And the whole thing goes boom cuz you put 40/60 instead

@The More You Know hmm, not sure I can answer that one, especially in the current "climate".

Light a small firecracker in your open palm and you get surface burns, close your fist around one and you lose your hand. I hope you can extrapolate the point 😉

It is also good rocket fuel

Imagine putting rust powder in your 50/50 mix

adding sulfur makes it one step closer to gunpowder Lmao

Yeah smell sulfer and get lung cancer

@@nathanholyland9493 True

Apparently it wasn't good for my moles, they'll never let me hear the last of it!

You still got all your fingers and toes?

@@antonycasanova4067 Haa...! ;) YES! and eyes, too, with a lot of luck. My eyebrows long ago grew back.

LOL

I'm assuming that you grew up in the 80's. I remember those days. Now days, if a kid did that he would be court ordered into therapy and he and his parents would be branded as antisocial. I miss the freedom that we had back then.

@@antiqueantique7786 Even better, I grew up in the 50s & 60s. All I had to do was go to the drug store pharmacy, purchase a gallon of dry potassium nitrate, another gallon of dry sulphur, and confectionary sugar from the grocery. Eventually, I substituted charcoal for sugar. That was much better. And I was a good normal American boy! ;)

BrainDoesStuff not really.he didn’t mix them well,didn’t grind the powders till they are fine,and didn’t seal the containers so the nitrate got muist

Rocket candy

Ahh so make sure you do it a hospital rather than at home for when it does explode while you are holding it in your hand... "Can hold in your hand for a moment road flare"... Followed with "can sometimes explode"... LOL....

@@edwardortman2593 - I have actually made and held these Home-Made road flares. If properly mixed it is quite safe.

That's what the "tare" button is for.

@@andyl5645 the power button IS the tare button in those scales

Would adding some Hydrogen Peroxide to this mixture make it burn more volatile? It's also an oxidizer, very strong one. But it does break down into water so that might make it fail.

Is 50/50 the optimum mix? I mean, as propellant, what is the most effective one?

@@osamabinladen824 Hello dear subscriber to my channel! No 50/50 is not the optimum. The optimal mix of these two components would be around 65% KNO3 and 35% sugar. It would work better than shown in this video if the components were dissolved in distilled water and the water then evaporated off at the lowest possible temperature, at around 100 degrees Celsius. You shouldn't exceed 120 degrees Celsius as the KNO3 can deteriorate. But sorbitol may be a better fuel than sugar because you don't need water to mix the ingredients together homogeneously. I am writing this because remaining water can negatively affect the burning reaction and sorbitol has a melting point of around 100 degrees Celsius. The ideal ratio of KNO3 and sorbitol is the same as stated for sugar. First melt the sorbitol at the temperature mentioned and then stir in the KNO3 evenly. Disclaimer: I decline any responsibility.

Well heard Michel :)

Yea michel

Or, an even better method to get it to burn super hot and produce a lot of smoke is 40% sugar and 60% potassium nitrate and cook them together in a frying pan until the sugar carmelizes, you then should pour it into some sort of container such as a toilet paper roll with tin foil on the bottom. Then you wait till it hardens in the fridge for a bit till it hardens from which you can light it off and kabam super smoke bomb/extremes heat

Mr.Techaky Thanks for the idea.

@@ClayishWall I've tried this. My mixture hardens like a rock but when I light it nothing happens AT ALL. can you help

@@mrshowtime7465 imma be completely real with u, I don’t even remember making this comment, but I got my source from somewhere online so the best advice I can give ya is just to look it up somewhere, sorry

@@ClayishWall lmao 3 years ago

me too it helped me( , from Algeria,) in my physique project

Matt Miller Why you have cops?

@@osamabinladen824 cuz neighbors are programmed brainwashed libs

I’m from San Francisco California and the cops don’t care here unless ur not doing it a safe place where it doesn’t interfere with other people which u should always. And always say it’s just fireworks I found, don’t say ur trying anything

A drop of water added for better mixing and end up burning better when it drys or ignite when water is present?

@@mckarthy5771 when it drys im pretty sure

Officer Patty just heat the mixture slowly over a hotplate stirring connstantly until it turns dark brown.and pour the molten material into a suitable container.

I tried doing that, however i get alot of air bubles and i had my rockets explode due to that reason: (

Officer Patty you could tey using a metalic container. L Then you can continue to heat the container until the air bubbles bubble out. Or you can place the rocket engine into a vaccuum chamber whille its still hor and vaccuum out the bubbles. Vaccuum chamber can be created with a glass jelly jar, and an old refrigerator compressor for cheap.

@@HDRNX Dude.... or you can just pour the mixture into a cardboard tube and put a large wooden dowel in it. Damn, must you make things so overly complicated. -_-

@@mr.techaky7655 yes but some of us enjoy overengineering.

Me tooo

I got it right back in the early 70's too :) Made pipe bombs detonated under a concrete slab in the garden, those were the days :)

Wat it deflgration meaning?

its a pipe bomb without the pipe lol

making it as light and streamline as posible is the easyest way to get delta V

That's why I'm Lookin bro! Be ready, you know!

Yeah but some countries remove this kind of product to public selling. Since stupid terrorists (collegial students too) did bombs or smokebombs. Yeah, some are lower lifeform and still doing silly weapons... With new reglementation in Canada we can have the stump remover but we have to show a passport or driving license + health card + proof of residence + what the use of the product. A little more and they would ask for the color of our underwear... It's more easy to go at Walmart and get instant cold pack (ammonium nitrate) with Windsor salt-free potassium chloride. At least, they don't ask you anything.

@@heritagekebek9979 Nice

Michael Cote Make it as big as you can, the worst that could happen is that you blow up the sun ;)

First step is to calculate in metrics

You'll need to amke a good nozzle as well for that ssize and height. Not just about the fuel.

So you want to send your fat ass wife into orbit as well I see?

People like you ruin it for everyone else.

sugar and sugar alcohol are different things though

Dave T I’m pretty sure you flunked chemistry class

thanks for fuse info. but whats the other 40%?

You just said make it into a taffy then it works better NOT in a taffy??!? Which is it??

@@andyl5645 I don't n't know how the 'n't' got there -- I meant do. Thanks n't

Not much. Charcoal is another source for combustible fuel but it has much less energy than sugar. The key to getting a faster burn would be to powder the sugar and then use a much more serious energy input. Like maybe an electrical discharge from a welding stick

65/35

The potassium nitrate provides oxygen for the sugar to burn. ive made rockets with it which was pretty cool

Pain in the RC What happened when you did that is that the sugar grains would be alone in midair, meaning it had all the air it wanted. Look up waxfire, pretty much the same thing

The optimal ratio is about 65%KNO3 to 35% sugar. Disclaimer: I decline any liability!

Yes, ty - wich reagents you use

most pros would disagree with you, for rocket fuel 65:35 is the accepted optimum ratio.

@@matoko123 i did some real tests, idk why but im wrong. i guess for some reason its better to have an excess of fuel

@@anthonyhadsell2673 There must be a difference between theory and practice. I suspect other variables are involved that the theory doesn't take into account

And sulphur. Try some napalm.

60:40 is better cause it burns longer means longer flight time
