Lol, I love how you just added a billion search terms in the video description. Gummy bears work great, by the way. *sigh* Just wish KClO4 wasn't so difficult to synth. Fun stuff, that.

yea im in nz

its near impossible to get

[BenHBX]

one of the products is manganese heptoxide, which oxidizes anything organic, so if you put some on a tissue or a piece of cereal it'll catch on fire

[JLsays6]

got a video of me putting a daisy into some

[dkamagic]

so how did you get that H2SO4?

[JLsays6]

school lol

[katuroo]

Johnny was a chemists son

but Johnny is no more

what Johnny thought was H2O

was H2SO4

ghehehe

sulphuric acid reacts with permanganate but the reaction you see is not that.

sulphuric acid reacts with permanganate to from manganeseheptaoxide, which is a very powerfull oxidiser. that reacts with almost everything it touches. and that is what you see.

with KMnoO4 and H2SO4 u must put '' ACETON '' to make fire

[lyrison]

@tjiddles25 I agree. I just preformed this reaction in a clean glass vessel about 30 minutes ago, and there were some visible fumes, but it formed an oily green substance (Mn2O7). Since the Mn2O7 reacts with organic substances, usually resulting in combustion, there must of been some kind of organic substance in the vessel.

Hey I'm also from NZ.

Did you buy your H2SO4 from clarks product LTD.

I can buy KClO4 with ease but do you know where to get KClO3 in NZ

[diapysik]

@Fenris121 kclo4 is easy pottasium chloride electrolyis for longer than the chlorate takes but kmno4 is alot harder

@Nguli34689

wow what kind of scale did you use? You must work in a lab right?

[Scrap5000]

weak

[Nguli34689]

@katuroo That sounds familiar. In the 1960's we had a small book of lymerics with "Willie" as the person in question. This Willie would do things like suck the mercury off the thermometer for instance in that book. Here is how another version from this book went:

"Poor little Willie We shall see Willie no more. What he thought was H2O Was H2SO4."

[Nguli34689]

I have done an experiment with

NO MORE THAN 200 micrograms of Lithium Aluminum Hydride with concentrated Nitric acid dropped right on this such small amount. The result was like a firecracker explosion. 200 micrograms is 200 MILLIONTH'S of a Gram. Yes, that small amount and it still exploded. This is why one has to respect chemicals and chemistry.

@Darcshadow5

I don't know about that since potassium only has a 1+ oxidation state. And the position of the roman numerals in that would suggest the 7+ and 5+ charges would be on the potassium.

Is that the top part of gamo bullets container you're doing the reaction in?
