Picture of Diy 4th of July pyrotechnics
Want fireworks, but your parents won't let you buy them? Sick of high prices? 10pm on the 4th and all the stores are closed? Whatever your reason is, you don't have to miss out on the fun. You can make your own fireballs for free!



Step 1: Gather materials

You only need:

-Sawdust. Finer particles are better, but anything will work.
-Trash can. Steel is best. This is sort of optional.
-Torch or piece of wood. You may also need a lighter or matches. (my torch has a sparker)
-Safety glasses. Better to be safe than sorry. Use a cheap pair, they might get ruined
-Large bucket of water, hose, or extinguisher. For when it gets ugly.

This site is for real experiments and cool stuff.....not for drunkin hillbilly antics!!!
Actually, I would think that this site is meant to allow people to give instructions on how to do things. This guy made one on how to nearly kill yourself with a can of sawdust. I think that would be legit. Trust me, there are dumber things on this site than lighting sawdust on fire.

I am almost certain that this is illegal( or incredibly stupid), Nevertheless this is AWESOME

Try doing this with a shop-vac set on reverse.

ummmmmm in case u dint know pyrotechnics is when stuff EXPLODES this doesnt explode.just fire fire is cool though but still i was hopin for a big boom.BIG BOOM!!!!!!!!!!!
that is not right!! pyrotechnics is anything that involves fire. just look at airbags! they aren't explosive, yet they are pyrotechnic devices
but they do use an explosive charge to deploy.
it isnt explosive. it is jsut a combustion reaction that instantaneously releases gases in excess of the airbag's volume. esplosives require some form of compression. While you could technically argue that it is explosive, i do not consider it so. However, I am not the world.
What makes airbags inflate is a semi-explosive chemical reaction triggered by electricity.
explosion: rapidly expanding gases
Arent airbags deployed by um air?Fire?I think AIRbags are deployed by a sudden rush of air.Not sure though.......maybe your right.......doubt it but ill check wiki......
If you've ever had a crash in a car or watever, and the airbags went off (like when my mum crashed-i was in the passenger seat) there is loads of smoke from the airbag's explosive charge. But, you are kinda right, because the explosion is surrounded by air, and when the explosion happens it pushes the air (along with other gases) out in all directions,forcing the air bags to pop out infront of your face (hopefully). Oh, and just so you know we were both fine, but the car was completely destroyed, and i had internal bruising in my knee. FUN FUN

Oof, thats not fun. Its not actually smoke, most of it is a very fine dust.
No. Airbags are deployed by nitrogen explosively evolved from the decomposition of sodium azide (NaN3). This also creates free sodium that immediately reacts with moisture in the air to create sodium hydroxide (NaOH), a strong base.

But when you make NaOH from Na and moisture(H2O) you will have one hydrogen atom left.

And?....it immediately combines with the other hydrogen from the reaction next door to make H2....and given all the energy flying around, two to those xpmine with a passing O2 to make....water.
"xpmine" ???
combine. %%$%$ iPhone keyboard!
LOL Desktop Computers FTW!
dude.the only chemistry i know is fire+gunpowder=boom
Sorry to rain on your parade (that won't stop me though...;-) ), but fire + gunpowder actually = "whoosh" or maybe "foomp". Fire + gunpowder in an enclosed space = boom. And smoke. Lots of smoke.
i no that!im not stupid.....usualy. i just simplified.
Truly a crude way of explaining such exothermic reactions.

I Like It! _
yep!im not a big believer in school or homework.
Lol, you're right about pyrotechnics being about fire (pyro=fire technics=study/use of) but airbags DO have an explosive in them!
They are very powerful, in fact if you put your hands in front of the airbag and it goes off, your arms will snap and your face will sustain fractures and breaks!
dang u are right.......sorry.plus me and godhart had the whole fire/explosive discussion already
yeah, i know you already had the discussion, but my comment made you learn about airbags :D
Tru dat!!!!!!!!!!!Well u learn something new each day.
sparklers are technically pyro(fire)technics.


they dont explode!!!!!!! why cant they make explosive stuff legal in my state??? oh yeah!!!! the fed is corrupt a bunch of liberals,rights takin,govenment spending,tax raising slime balls! no offense to any democrats;)
Pyrotechnics is the science of materials capable of undergoing self-contained and self-sustained exothermic chemical reactions for the production of heat, light, gas, smoke and/or sound. Pyrotechnics include not only the manufacture of fireworks, but items such as safety matches , oxygen candles, explosive bolts and fasteners, and components of the automobile safety airbag.
stil explosions r better
they are definitely better at maiming a person *yes*
hmmmmmmmmm u gots to be smarter than the explosives to avoid that
even professionals get maimed now and then...some things are unpredictable...
But they are still more fun
I suppose.........as one gets older, with death looming a bit closer, they start to make attempts at avoiding it (especially since we heal slower at an older age ;-)
That sounds about right, But I'm not that old yet :D
