Step 1: Matches!

Picture of matches!
ok so get the matches and cut the heads off like so.

then grind then up with knife or somin till made into a fine powder

Step 3: Combine

now combine the two and light.


I AM NOT liable/responsible for anything you do with this illegaly

Step 4: Test

heres a video of it in action caution it gets hot!

the smoke is the paper burning

Step 5: Colors

ok so now im going to tell you how to make you're flames cooler! now take you're blue powder and what not and get a whole bunch of different colored powder now this is important to make it gradually change collors take thin cardboard or thick paper{very smoky with paper} and wrap the different layers as shown. by gradualy i mean some what fast. you should also tear the paper into a small strip. fold down the middle.

Step 6: Fold-N-Roll

once folded roll into tubelike shape. fold and tape any open ends shut.

Step 7: Add the powder

Picture of add the powder
now add the blue powder. roll the tube up about half way. now add the red powder or what ever collor you have. roll the rest of the way and tape. youre final design should look like this

Step 8: Light

here is the final product , i had fun making it and i hope you do to.its kinda flamyish after it burns out so be carefull, and once again im not responsible for what you do. have fun

im pretty sure salt would turn blue also... thats what i heard at least
salt turns red. copper powder would turn blue.
ya i've had a continuing argument that copper burns blue or it burns green..
copper burns green

Actually table salt turns bright yellow. Copper compounds are greeny-blue, the only good red flames come from lithium and strontium which are hard to get hold of. Note that sodium chloride, copper sulphate and lithium nitrate are all "salts" in the chemical sense of the word, hence potential confusion.

Mmyeah, salt turns bright yellow.
As PKM said, Strontium chloride makes red, but there's also:
  Copper chloride - blue
  Copper sulfate - green
  Potassium chloride - purple, and
  Copper sulfate - green

And to make colored candles, just boil the metal shavings with water, then soak a wick in the solution.  After that, just cover it with wax, and you got a colored candle!

Hey! Theres a little somthing called... PROPANE! and... BUTANE!... and.. METHANE!!!.... They all burn blue! Even purple in the case of propane.
And... ALCOHOL!

yeah... untill you blow ur self up? then what u do???
well, thats your fault. If you blow yourself up you're too stupid to be playing with propane in the first place.
well a propane blowtorch is really easy to modify, i am inventing a new nossle for them and i found is relatively easy to modify a torch safely. ( i am using a welders mask and welding gloves, over-protective but safer). anyway things burnm in differnt colors based on chemical composition and flame intensity,

from least hottest to most

yellow-red-blue-light blue- white

(white is so hot it melts hardened flame-proof and (supposedly)  melt-proof epoxy see here )
agreed!
 when things burn really efficiently and complete they burn blue. Its just that it does look supprising, as that looks like a jet. 
coke burns blue.

For some wierd reason I read it as rainbow knife. Don't ask me why. So yeah that's why I posted that.
