Glad you asked! The stump remover is already >98% KNO3 to start with. I did not record how much was lost in the process because I used the purified crystals as a lab reagent and saved the remaining dirty stuff for pyrotechnics or things that don't require KNO3 of high purity. Potassium nitrate will not evaporate from a solution, just the water, so virtually none is lost at all using this process. Repeating the process will continue to purify it but really isn't necessary in this case.
Fantastic video! It was really cool to see the crystals forming as you decanted off the water. Potassium nitrate crystals are really pretty. It would be cool to look at them under a microscope. Remember. If you aren't part of the solution you're part of the precipitate!
Great video! When I perform procedures like this, I typically vacuum filter the hot solution. This removes suspended particles and other solid impurities. I've seen a brownish murky solution of nitrate fertilizer go to nearly clear after just to passes. And of course you can always perform multiple crystallizations if you need a really pure product.
I tried this in winter time in an unheated garage. I prepated some heated bricks to set the solution on to keep it from cooling to fast. Well about 36 hours later i got single crystals six inches long, an an inch thick.
I would recommend another recrystallization. Since you didn't rinse the crystals with ice water after decanting the solution, the wet crystals have the impurity-filled solution stuck to them. Thus the dry crystals will have impurities in them
There is something I don't understand. Where have the impurities gone? As fa as I can tell, they are still in the mixture. You poor the liquid with all is content (including impurity) in a different beaker. What am I missing?
Yep! Not to rip on a dead guy, but The King of Random was basically just a consolidation of concepts taken from other channels, or, even worse... just a bunch of shitty life hacks! lol.
What you make here is called Supersaturation solution which means dissolving the maximum amount of substance in the water…if you want to get pure Chrystal you need to add more distilled water, than after cooling , the kalium nitrate crystals clearly droppings to the bottom of the solution, you can pour out and collect those crystals but in your case because the solutions is Supersaturation, once you stopped heating , crystals are forming everywhere quickly, makes no chance to separation the Impurities ..
I freaking LOVE how everyone thinks Potassium Nitrite is a big secret and it's either super hard to get ahold of or magically going to disappear if someone finds out what company sells it 😆 you can get a 10 pound bag for $21 plus shipping and have it to you within a few days 😆 I can't get over the comments I've seen and things people have said in they're videos about Potassium Nitrite. Brothers and pyro sisters ... Potassium nitrite isn't going anywhere and its literary as cheap and in some cases cheaper then a bag of good potting soil. You can get everything you'd need to make several types of flash powder and black powder at home for under $80, and that's with buying sulpher and potassium nitrite in 10 pound bags. Trust me I just did it, and I use to make m-100's 8 years ago. I am not going to be mixing up flash powder until I get my ATF licence this November because I'd rather not risk my chances at following my dreams of working in the pyrotechnics field however I did mix up 25 grams of B.P. tonight and light it all off at once since it was my B-day and I wanted to end the day with a whoosh. Lol it wasn't really a woosh because B.P. has such a slow burn rate and I didn't get my willow charcoal into a fine enough powder. Next time I won't make that mistake and I am going to add some Zinc to the mix and see if it turns the flame green because that would be epic to see a Black powder with a green flame
Hey, great vid! was wondering how you went about the waste disposal--I'm not sure what to do and I don't want to start any projects without knowing how to finish them. Thanks!
Well you have the refrigerator pump, it makes really good vacuum on the other end use it for real vacuum filtration, I do that all the time. After some time it is necessary to add some motor oil to the pump via vacuum side and eventually it will seas from rust. WD-40 helped My one but after year of service I think I need a new one. At the beginning I was worried about the temperature of the pomp but now I run it constantly so it is too hot to touch it. It still works.
@zhmapper. Okay, maybe I understood this wrong, but get as many crystals as you can at room temperature, and refrigerate the excess solution overnight to obtain more?
The room temperature collection was only because he was in a hurry, and is not necessarily needed But, the purity of the crystals will be somewhat better than the crystals at the end of the recrystalization. One could take the saturated solution at the tail, heat it up, and boil off much of the water until the remaining solution is saturated again at 100c with crystals beginning to form, and then pull it off the heat and let it recrystalize. Finishing the first Recrystalizing of the tail end solution, if added to the first recystalization, will result in a better yield collecting much of your starting material, but the recrystalize tail end won't be as pure as the the first batch because the contaminated solution is more concentrated with contaminates. But recrystalizing the tails of the tails will provide increasingly diminishing returns with increasingly dirty product. Obviously the small amount of finished recystalized tail ends can be recystalized a second time to increase their purity before adding back to the first batch. What is left is probably best to be evaporated forming dirty impure crystals which can be used to fertilize soil with Nitrogen and Potassium or used to make pyrotechnics.
I believe that you'll find that the container is the same as a common style of container for motor oil. Paying a container manufacturer for an already existing style would be a cheap option.
Shouldn't the crystals be rinsed with cold water to remove the contaminates in the liquor that is sticking to the crystals? If you succeed in removing 90% of the liquor, by decanting only, you have removed only 90% of the soluble contaminates at best (assuming the re-crystallization perfectly excludes the contaminates).
dude... this is absolutely fascinating. I didn't know anything about purification... many thanks bro! OUTSTANDING. if you would rapidly go from the 100 degrees to 0 would it increase crystal production?
Actually, cooling rapidly is a bad technique in recrystallization. If you cool rapidly, the crystals will form very rapidly, and will trap impurites within them, giving you a less pure product.
I must have missed something in what way was this purified it was definitely recrystallized but unless the title is wrong you definitely skip the part where you got rid of the impurities🤔
I notice in this video as well as a couple of others, using approx 200ml of water is average for 450g of stump remover. What would be the result, and how would you remedy adding a too much water?
The result would be that you wouldn't be able to get as much out of the recrystalizations. That's it. You would just end up with a saturated solution that may not precipitate as much of the product. Essentially, you would just need to boil off some of the water and continue with the recrystalization.
Thank you for doing this video. It worked no problem. I also learned something else during this process, I need beakers! My wife was not real thrilled with me using her kitchen gear. Do you have any suggestions as to the best size beakers to get and how many of each size? I will be mainly be doing things like this.
You can probably get away with a single 1000mL beaker. Personally what I use is 1000, 800, and 500 and 250. Sometimes its nice having more than one nearly the same size you you can decant supernatant from the 1000 into the 800 or you can filter a solution into a beaker. If you don't have 2 beakers you can't filter a solution.
On eBay you can get a nice beaker set for right around $20. They usually come with a 1000ml, a 500ml, a 250ml, 100ml, 50ml, 25ml and a 10ml. They take a while to arrive though. EBay is the way to go though when it comes to buying cheap beakers and flasks.
Can you boil off the whater after recrystalisation cleaning and use stainless steel pots since you dont use acids ? Or does KNO3 attack stainless steel more than NaCl
Great video! Do you happen to know approximately how much of the stump remover is lost during re-crystallization? I know that the total mass after the saturation etc. will be lower because the impurities are removed but is any actual potassium nitrate lost (due to evaporation etc...)? If so, would it be smart to cover the liquid until it has crystallized? Also I know that some purification methods should be repeated, is this the case for stump remover? ~80+% purity works for me. Thanks!
Stump remover is not 100% in the pyrotechnic (firework) usage. As far as usage of stump removal, Spectracide claims 100%, but it still has some impurities. Also, there is a problem with the decanting . When allowing the crystals to dry if should be in a very dry area ( little to no moisture in the air)
Why mark fluid ounces on the jug? Because if you read the directions you are supposed to add water and shake before applying the slurry into holes you drilled in a stump.
It's just a crystallization, I am very perplexed about the purification. Also the crystals should be washed with a different solvent using a filtering system. ..
I have kno3 round pellets that says 99.4% pure. If i grind it and go through your process will it make that much of a difference in performance of Black powder and Rocket fuel???
No. 7 years too late but no. Just go online type Potassium Nitrite in google it'll pop up a 10 pound bag of 98% Potassium nitrite and it comes in small pellets, you can either use his method or use a mortar and pestle or coffee grinder and turn it into a fine powder if you are just using it for BP no need to do his method thought I am going to try this and see if it has an different effect then the powder. My guess is it either won't or if it does its only because I will be able to get the crystals into a finer powder with the crystals. I am going to try a flash powder with both as well just to see if that has a different effect on how well it burns. I extracted about 30 grams of flash powder from fireworks this year and I added in a spoon full of my potassium nitrite and a spoon full of Indian Dark Aluminum powder today hopeing that I wouldn't ruin it and I decided to make a triangle cracker by taking a mortar fuze from breaking the fireworks down and putting it through a small hole in the corner of an envelope and then I took about 12 grams of my mixture and folded it all up and then I decided to tape it up with electrical tape nice and tight to stop any powder leaking out and before I did it I thought "hmm maybe I should test a small amount 1st so I took maybe 400mg of the powder and lit it and it flashed so damn hard I decided maybe it wasn't the best idea to do the triangle cracker I made near my house when it isn't legal to do fireworks or there isn't rain or snow on the ground because people could care less if it were those situations but mid summer during a drought year when we've had fires all over the state already. So instead I took a sticky note, rolled it up backwards so it stuck to itself in a cylinder and I used electrical tape to hold it in place well it was still on the pen and pulled it off 1/4th the way and bent the end up and taped it and then I filled it with the flash powder and took a firecracker I broke in half and put it on top of the powder in the tube and taped it in the tube so it looked like an extra long firecracker with electrical tape all around it and lit thay instead and I gotta say I am damn lucky I didn't just light the triangle cracker that had about 20 times the amount of powder in it because that little fire cracker made a thud that I was worried might get me introuble 😆 it was about 10 times more powder then a normal little firecracker so if you think that probably had 500-700mg of powder and the triangle cracker was way fatter then ones youd normally see my guess is when I actually do it its going to make a boom that shakes windows 😆 I am actually going to take it to a feild nearby to avoid any issues because I was absolutely shocked by how adding a scoop of those two powders made the powder extracted from fireworks so much stronger then it already was. I am glad for now I live in am area where it would be looked down on to make giant salutes because I'd love to use KCIO-4 in F.P. instead of KNO-3 however once I get my ATF licence in Nov. It won't matter anymore and I am then moving 9 hours away to where I am away from highly populated areas and it will no longer matter if I decide to go outside and light of salutes off. I will also have a bunch of different jobs I can get out there because my entire family lives out there.
cool thanks worked nice lovely long claer crystaiis.but once you have done this is 100% or could do tihis methed more than once for even beter KNO3 ? once agen thanks i never would have though i would dig chemistrey so much never to late to lern something new.
A lot of brands have dirt mixed in with it, which can be detrimental to some reactions. Every time I dissolve and filter mine there is always a lot of insolubles in it. About the only way to buy extremely pure KNO3 is to get it from a chemical supply company that specifically supplies it for chemistry. I know I don't want dirt in my KNO3 when I make nitric acid. Lol
@cosmin0192837465 The steam is just water evaporating and unless you can cite your sources for the carcinogenic vapor, it's simply harmless gaseous water.
That is kind of funny that the container is marked in fluid ounces to sell a solid product... Then again, honey (a liquid) is sold by weight... so who knows... Maybe someone's just trying to see if we're paying attention.
Sorry bud, but purifying would mean you toss everything that doesn't drop before a certain temperature. You were just refining it. Still a good demonstration.
Mix in ordinary table salt, and the KNO3 will precipitate out of solution. It might take a lot of NaCl so keep adding it until you see crystals fall out of solution.
If I made a solution from 46% potassium nitrate fertilizer and freeze it will I get a pure potassium nitrate crystals 🤔 or it will be stuck with the nitrogen
You end with too much of your product getting wasted in water you pour off. Here, Doug messed up a little by using too little water. Another 15ml of water would have kept the crystals in solution a couple minutes longer, resulting in a much more pure product, but slightly less crystals.
Hey! I'm trying to make sugar rockets, and I was wondering why mine didn't light off with a match. I tried melting, and not as well. 65%-35% KNO3-Powdered sugar was the mix. The KNO3 I got is EK fertilizer, 13:64. It has 13% nitrogen, and nitrate-nitrogen, and 46% water soluable K2O, Potassium oxide, and from that 38,2% potassium. Just smoke and black goop, and sparks. But it would stop even smoking if I didn't move the black goop around.
Loutcho Bix The idea is that crystals tend to be very pure, so when you recrystallize, you mostly get the substance you're purifying in the crystals, while most of the impurity remains in the liquid. When you pour off the liquid, you're pouring off concentrated impurities. Of course, some of the stuff you're purifying is still dissolved in the liquid, so that gets tossed out too. Basically, the process concentrates what you want in the crystals, and concentrates what you don't in the liquid. Of course, this isn't perfect, you still get impurities in the crystal and the stuff you want in the liquid.
Great idea. I wonder if this stump remover idea is cheaper than buying potassium nitrate from a firework source, but then I don't know how much purity is required for good black powder. You would definitely have to ball mill it into a fine powder to make it firework grade.
Eduardo Costa Yes it is. But when you are simply trying to clean up impurities it is not necessary at all. its a waste of time. It does not buy you anything,
Clown Whisper It will always worth that is what chemistry is about every good chemist know that math and science are just different ways to see the same thing. They need each other to create a really quality product
Eduardo Costa The only reason there would really be to do the stoichiometry here would be if you were writing a paper. If you were doing that, you would not really need to because you wouldn't be using stump remover, you would use reagent grade stuff, Thats all I am really saying,. Recrystallization is one of the more laid back things that I do. I enjoy the process lol!!! Wow I just realized what a nerd I must be,,,
Wow you really think it is easier to painstakenly add more and more of a salt trying not to overshoot when you could just look up the solubility data instead? You waste 10 mins removing excess salt you add when you could have taken 10 seconds to look up the solubility info.
It's a re-crystallization, so all solids should be 100% pure KN03. However, he didn't rinse it before decanting, so impurities were never washed away, thus the KN03 is impure. If you wash it, it should be pure. I don't know what to wash it with through, its is slightly soluble in ethanol so that seems like a bad idea
Its cheaper to buy it. It's sometimes used as a food preservative or more common as a fertilizer. But you could mix potassium carbonate with nitric acid, but that's not safe.
"chemistry is more important than my phone" i like the way you think man
Glad you asked! The stump remover is already >98% KNO3 to start with.

what type of filter ? coffee ? cold water wash then dry.
wait I'm confused what are you asking?
TheChemistryShack
+TheChemistryShack Hi and thank's for that answer :]! Would it be a good choice to rinse the crystals with ethanol instead of cold water?
Wow, I didn't realize this was posted in 2010 until the end of the video.
Damn, that's some decent quality for back then, almost 12 years ago.
There is something I don't understand. Where have the impurities gone? As fa as I can tell, they are still in the mixture. You poor the liquid with all is content (including impurity) in a different beaker. What am I missing?
Literally 75% of "The King of Random"s videos came from Doug's lab.
Yeesh this didn’t age well
Zzzz lol, i was thinking the same thing.
Yep! Not to rip on a dead guy, but The King of Random was basically just a consolidation of concepts taken from other channels, or, even worse... just a bunch of shitty life hacks! lol.
Good job.
@@jhyland87 still a lot better than blossom/5 min crafts
What you make here is called Supersaturation solution which means dissolving the maximum amount of substance in the water…if you want to get pure Chrystal you need to add more distilled water, than after cooling , the kalium nitrate crystals clearly droppings to the bottom of the solution, you can pour out and collect those crystals but in your case because the solutions is Supersaturation, once you stopped heating , crystals are forming everywhere quickly, makes no chance to separation the Impurities ..
Great bit of simple of chemistry. Fun for all the boys and girls! Atta chemist

In some parts of Europe it's banned in a pure or ready to use form.
Hey, great vid! was wondering how you went about the waste disposal--I'm not sure what to do and I don't want to start any projects without knowing how to finish them. Thanks!
Hi potassium nitrate is a great fertilizer, dilute it slot and feed to the grass!
So did you filter through , Into the jar ,.., and then into second clean beaker ?
Well you have the refrigerator pump, it makes really good vacuum on the other end use it for real vacuum filtration, I do that all the time. After some time it is necessary to add some motor oil to the pump via vacuum side and eventually it will seas from rust. WD-40 helped My one but after year of service I think I need a new one. At the beginning I was worried about the temperature of the pomp but now I run it constantly so it is too hot to touch it. It still works.
found Doug's old channel
I wish you were still around💜
Maybe try decanting before breaking up the solid.
@zhmapper. Okay, maybe I understood this wrong, but get as many crystals as you can at room temperature, and refrigerate the excess solution overnight to obtain more?

Nice video to watch,
what was the purity before recrystallization? if high enough, why purify anyway?
the company probably uses the same containers for liquid products they sell besides using th em to dispense dry products.
I notice in this video as well as a couple of others, using approx 200ml of water is average for 450g of stump remover.

Very good video! Could you, if it is not a problem, explain the procedure? I have kclo3 obtained from sodium hypochlorite! Thank you in advance!
You aren't using a thermometer as a stir rod are you?
I do. Works great
It's in fluid measure because you make a solution inside of the bottle.
Thank you for doing this video. It worked no problem. I also learned something else during this process, I need beakers! My wife was not real thrilled with me using her kitchen gear.

The company is spectracide if any of you didn’t know

Nice! What was your yield?
Why mark fluid ounces on the jug? Because if you read the directions you are supposed to add water and shake before applying the slurry into holes you drilled in a stump.
Yea, that's true although when you put the water in, you can't even see where its at. Lol
Thanks for uploading! But Does it have too form crystals when you cool the solution down?
was that a full bottle of stump remover or had you already measured out how much you needed before the video begun?
ARGH...! My head fucking hurts!
It has anti caking agent, but yea it's pretty much pure, so after recrystallize you shouldn't lose much
It's just a crystallization, I am very perplexed about the purification. Also the crystals should be washed with a different solvent using a filtering system. ..
i did this and it worked thnx alot, but what could u do with the crystals?
can i grind the crystals into a fine powder without an explosion? and also very cool video :)
I have kno3 round pellets that says 99.4% pure. If i grind it and go through your process will it make that much of a difference in performance of Black powder and Rocket fuel???
Great video...Can I use fertilizer with 27% KNO3?
No. 7 years too late but no. Just go online type Potassium Nitrite in google it'll pop up a 10 pound bag of 98% Potassium nitrite and it comes in small pellets, you can either use his method or use a mortar and pestle or coffee grinder and turn it into a fine powder if you are just using it for BP no need to do his method thought I am going to try this and see if it has an different effect then the powder.

@k1ng401. Some brands are even 99 or 100% KNO3, so recrystallization is somewhat pointless
A lot of brands have dirt mixed in with it, which can be detrimental to some reactions. Every time I dissolve and filter mine there is always a lot of insolubles in it. About the only way to buy extremely pure KNO3 is to get it from a chemical supply company that specifically supplies it for chemistry. I know I don't want dirt in my KNO3 when I make nitric acid. Lol
I've got fertilizer does this work for it beacuse has some nitrogen and ....
does it work this way ????

@cosmin0192837465 The steam is just water evaporating and unless you can cite your sources for the carcinogenic vapor, it's simply harmless gaseous water.
@luftwaffe1111 That's Dihydrogen Monoxide!! Dangerous stuff. :)
That is kind of funny that the container is marked in fluid ounces to sell a solid product...
Then again, honey (a liquid) is sold by weight... so who knows...
Maybe someone's just trying to see if we're paying attention.
Cool shit!
Sorry bud, but purifying would mean you toss everything that doesn't drop before a certain temperature. You were just refining it. Still a good demonstration.
Hello Doug's lab.
Does it need to be distilled water
nice
I'm doing an experiment at school and I have to turn KNO3(aq) into crystals. How would I go about that?
Mix in ordinary table salt, and the KNO3 will precipitate out of solution. It might take a lot of NaCl so keep adding it until you see crystals fall out of solution.
boil it till its dry
it looks like a vitamin container with the label taken off.
If I made a solution from 46% potassium nitrate fertilizer and freeze it will I get a pure potassium nitrate crystals 🤔 or it will be stuck with the nitrogen
I use a steel pot an have done this many times
Does it release toxic gas
@coolhand2323mods I'm in the process of making videos about that. :)
How to Make yellow Sulfur powder into White Sulfur powder.??
You didn't wash them........
Where I can find stump remover?
In Greece?
nick mantzouratos hard to say. A lot of us live in the U.S. but I can look leave a comment on RUclips for you, maybe someone else will know.. 😉
what happens if you used way to much water?
You end with too much of your product getting wasted in water you pour off. Here, Doug messed up a little by using too little water. Another 15ml of water would have kept the crystals in solution a couple minutes longer, resulting in a much more pure product, but slightly less crystals.
Hey! I'm trying to make sugar rockets, and I was wondering why mine didn't light off with a match. I tried melting, and not as well. 65%-35% KNO3-Powdered sugar was the mix. The KNO3 I got is EK fertilizer, 13:64. It has 13% nitrogen, and nitrate-nitrogen, and 46% water soluable K2O, Potassium oxide, and from that 38,2% potassium. Just smoke and black goop, and sparks. But it would stop even smoking if I didn't move the black goop around.
If it's purification wehre do the impurities end?
exactly what i was thinking?
left with the crystals after evaporation would be my guess
Would depend on the solubility characteristics of the impurity....
the water evaporate withe the impurities. So the impurities that can't "evaporate* juste stays... if I understand it right
Loutcho Bix The idea is that crystals tend to be very pure, so when you recrystallize, you mostly get the substance you're purifying in the crystals, while most of the impurity remains in the liquid. When you pour off the liquid, you're pouring off concentrated impurities. Of course, some of the stuff you're purifying is still dissolved in the liquid, so that gets tossed out too.
Basically, the process concentrates what you want in the crystals, and concentrates what you don't in the liquid.
Of course, this isn't perfect, you still get impurities in the crystal and the stuff you want in the liquid.
So doing this over and over would make a purer end product?
how much water do i have to use, and the temperature for 3 kg of stump remover?
Pedro Carvalho do the math dude.
@@juvnchy for real!
does anyone know if this will work with potassium nitrate fertilizer?
It should,.but you will have to do it repeatedly to get of the contamination out.
this is purifying kno3 this is just how to extract it from stump remover
Stump remover is already kno3. He is just purifying it for better results with experiments.
Is this possible with potassium Chlorate ??
yes
I found out through experience- if you use to much water an boil to hard you'll lose allot of crystals..
Rather then wait for it to dry overnight, couldn't you heat it on the out plate to drive out the water?
Can I or any one just crush the crystals into a power and use it for a smoke bomb or smoke grenade
Yeah
Great idea. I wonder if this stump remover idea is cheaper than buying potassium nitrate from a firework source, but then I don't know how much purity is required for good black powder. You would definitely have to ball mill it into a fine powder to make it firework grade.
Polarcupcheck I buy mine on Amazon it's a lot cheaper than buying stump remover.
***** Where do you live ? It's banned in CAN apparently ..
I live in Massachusetts in the usa
Btw, I just purchased this same product from the same company... they no longer have the FLOZ marking listed, lol
I wonder how many times it takes to get 100% 4 5 10.
Yield?..
its easier to just heath the water and keep adding until no more will dissolve then let it cool. No math needed
Clown Whisper Chemistry is math
Eduardo Costa Yes it is. But when you are simply trying to clean up impurities it is not necessary at all. its a waste of time. It does not buy you anything,
Clown Whisper It will always worth that is what chemistry is about every good chemist know that math and science are just different ways to see the same thing. They need each other to create a really quality product
Eduardo Costa The only reason there would really be to do the stoichiometry here would be if you were writing a paper.
If you were doing that, you would not really need to because you wouldn't be using stump remover, you would use reagent grade stuff,
Thats all I am really saying,.
Recrystallization is one of the more laid back things that I do. I enjoy the process lol!!!
Wow I just realized what a nerd I must be,,,
Wow you really think it is easier to painstakenly add more and more of a salt trying not to overshoot when you could just look up the solubility data instead? You waste 10 mins removing excess salt you add when you could have taken 10 seconds to look up the solubility info.
How do I make nitrogen gas
Stalin did nothing wrong Not sure how you make nitrogen but I can tell you how to make methane.
how much purity is that kno3 ??
It's a re-crystallization, so all solids should be 100% pure KN03. However, he didn't rinse it before decanting, so impurities were never washed away, thus the KN03 is impure. If you wash it, it should be pure. I don't know what to wash it with through, its is slightly soluble in ethanol so that seems like a bad idea
ok thanks
Way too much nitrate , or add water the crystals will be way bigger
Could you use potassium nitrate from the internet or does it have to bee stump removal
the purer the better
Bee stump?
can this be used to cure meats?
probably but if your feeding it to people oter than yourself you should get the purity tested
Its called cryshtals!
and also about how much kno3 do you get from one jug of stump remover
About 1 pound.
Is the bottle not 100% KNO3?
Adah gak yg bisa ajarin aku bikin
Its cheaper to buy it. It's sometimes used as a food preservative or more common as a fertilizer. But you could mix potassium carbonate with nitric acid, but that's not safe.
soue bad am sourie
no
Spctraide😂😂
Oh meth crystals ;P
Maybe try hiding the brand emblem a little more if you want it to be such a secret,
jeez,
it's Spectracide for Christs Sake
Its more of a copyright thing so he can monetize the video :P
