if you put sulfur with a small peace of white phosphorus...it ignites...

Really sorry to hear about the mishap, mewrox99  I'd thought after seeing your
potato chip in Mn2O7 nothing would frighten you! Safety definitely needs to be everyone's number one priority, but I do hope you'll continue doing
chemistry in the future.
In other news, I found this reference on the wiki for potassium chlorate:
"Potassium chlorate can react with sulfuric acid to form a highly reactive solution of chloric acid and potassium sulfate:
2 KClO3 + H2SO4 → 2 HClO3 + K2SO4
The solution so produced is sufficiently reactive that it will spontaneously ignite if combustible material (sugar, paper, etc) is present."
Could be worth a try! I don't have any chlorate sadly, but I really want to build a chlorate cell (I just don't know what to do about electrodes).

Chloric acid and tissue paper......
I have try that way,but it rarely ignites.Chloric acid will only turn tissue paper into goey black substance actively.
No fire was generated.

Manganese heptoxide is simply to made and can ignite any organic compaund.
It can be preparated simply mixing some potassium permanganate with a few drops of concentrated sulphuric acid. The solution will turn dark green.
To test it, add a single drop of the green solution to some acetone!

This is REALLY REALLY dangerous, so only i'm going to do it:
a molten eutectic mixture of potassium and sodium hydroxide and then dropping in some magnesium. The magnesium reacts with the hydroxides to form NaK
which at 200 celsius instantly catches fire.
Ofcourse it also shoots out droplets of flaming NaK and hydroxides so while full of pyrotechnic charm this is incredibly dangerous.

Also as a part of the year of chemistry video competition my parents have let me do one last thing with chlorite. 0.5g of NaClO2/Ascorbic acid ignited
by a drop of water. I can also submit the footage for the nurdrage project

Cool.
That reaction your trying seems stupidly dangerous. I probably did one of the most retarded things in my entire life the other day which lead to my
accident. I think people are curious so I'll talk about it in detail
I mixed in total about 1g of NH2OH.HCl/NaClO2 together. Expecting they would ignite instantly when mixed i carefully with a long stick mixed them. No
heat at all. So I poured into a peice of filter paper and waited a minute. Nothing. So I decided to take outside and light it. I then noticed I
didn't have my camera and walked into my room (whilst holding it ) I grab the
camera and was seconds from the door when a self ignited in my hand, (small fire)
This has scared me.
After further thinking I hate to think of the two chemicals could have reacted. Ie BOOM end of mewrox99
If you think something will make a good youtube think it through in detail first.
I am very embarrassed to talk about this and that I could have done something so stupid!
I'm only 15 so decided and I'm probably not ready to be dealing with dangerous chemicals.
I got hyped up and didn't think things through.
I won't sell anything just pack away my stuff for a while.
Please don't judge me too harshly for this; everyone makes mistakes

@mewrox99: I do not judge you, I actually think that you are smarter than many older and more experienced people over here, or on other forums. I know
of people who just go on with dangerous things, even after two or three of such warnings. You, however, did have an embarrassing experience and may
feel retarted, but you consider it as a lesson learnt.
It's good to pack away your stuff for a few weeks, cool down a little bit and in the meantime read on and think of other new experiments (and keep
visiting sciencemadness  ). But the interest will not die, it will remain and you
will unpack your materials again and do new experiments.
The goddess of chemistry is beautiful, but when not handled with care, she can bite hard!

Sounds very interesting, NaK reacts very violently with water
Ins't easier starting from potassium and sodium if you have?
Anyway, this is very dangerous, do this only in a nitrogen or argon atmosphere!

I hear ya, i'll be taking the precautions necessary to be safe.
but yeah, i won't do this if i ultimately don't feel my precautions are adequate.
@mewrox99
Good to hear you're ok and still in one piece. By all means take time off and reevaluate your experimental approach. What we do is fun but its more
fun if we're alive to see it. Do whatever you need to do to absolutely secure your safety. The last thing i want is anyone getting hurt doing this
project.

The eutectic melting point of KOH/NaOH isn't much below the alledged ignition temp. I think it would be a questionable preparation.
If you're going to go through the trouble of making NaK, you can add using the potassium superoxide formed upon exposure to air to the self-ignition
list. It will light up/explode with pretty much any organic.

Alkali metal superoxides/peroxides is a good idea. Ill make some sodium peroxide and try that with a few organics.

A funny experiment is taking fine granules of Na2O2 and put this on toilet paper and spray some water on this (e.g. with a flower sprayer). Only
seconds after spraying the water on this, the whole mess inflames and burns with a very hot and bright flame. I did this experiment with 2 grams of
Na2O2 and was amazed about the size and intensity of the resulting fire.

The whole point is to get it to ignite. I'm trying to make fire, not really trying to make NaK.

Woelen's NaNO2 method sounds cool. Really need to get some nitrite sometime

Put NaK into water!
Na2O2....not NaNO2

I don't have NaK.
And even if I did, you gotta realize essentially the reaction i'm going for is this:
(molten) NaOH + KOH + Mg ----> FIRE!
NaK is just an intermediate.
@ScienceSquirrel I thought you hated my video presentations and demanded i produced write-ups instead.
Why are you helping me for this video?

I was thinking if you had some mixture that was just stable around the freezing point of water, you could place it on a nearby thermogenic plant and
start a fire that way. It's kind of a left field idea I know but it's seems conceptually possible to start a fire with the heat of a plant.
"Thermogenesis is rare in plants, but does occur in several species of Arum, and in the philodendron, as well as the skunk cabbage. The heat
generation of these thermogenic plants is not trivial, either. Recent measurements of the titan arum “Ted”, at UC Davis, showed the
inflorescence– the flower-like structure of the arum– could maintain a temperature of 32 degrees Centigrade (90 F), well above the surrounding air
temperature of 20 C (68 F). The skunk cabbage can do even better, maintaining temperatures as high as 35 C, even when the air temperature is below
freezing."

Thermogenic plants?

This is actually a good video idea on its own! 
Thanks! i'll look into this topic!

My plan is to make crude Na2O2 by burning sodium. Ill try a few things (Woelen's tissue experiment, acetone, ethanol, sugar) and I will also be doing
chromyl chloride and sulfur soon.
EDIT: update!
I made some crude sodium peroxide but had no luck with it. It bubbled in acetone and ethanol, would burn with magnesium when a drop of water was
added. Ah well.
Sulfur and chromyl chloride video being sent to NurdRage.
