Introduction: 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!

WARNING

I'M NOT LIABLE FOR YOUR STUPIDITY. DON'T DO THIS UNLESS YOU ARE A TRAINED PROFESSIONAL. I ASSUME NO LIABILITY!

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.

Step 2: Technique

Grab as much sawdust as you can in your hand. Sprinkle it over the torch. Pull the torch out after a second or so (when it lights). Try this unlit a few times to get the hang of it. As soon as you start sprinkling lean back. You don't want to lose hair.

Step 3: Do It!

Well, thats it. Now just go OUTSIDE away from trees or other flammable things and do step 2 with the torch (or piece of wood) lit.

Show off to friends and family.

Hope you liked it. If you have any comments or concerns feel free to write them below.

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!!!!!!!!!!!

author

that is not right!! pyrotechnics is anything that involves fire. just look at airbags! they aren't explosive, yet they are pyrotechnic devices

author

but they do use an explosive charge to deploy.

author

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.

author

What makes airbags inflate is a semi-explosive chemical reaction triggered by electricity.

author

explosion: rapidly expanding gases

author

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.

author
Derin (author)npkeith2009-02-23

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

author
npkeith (author)Derin2009-02-23

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" ???

dude.the only chemistry i know is fire+gunpowder=boom

author
npkeith (author)sparky232009-01-28

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.

author
sparky23 (author)npkeith2009-01-29

i no that!im not stupid.....usualy. i just simplified.

author

Truly a crude way of explaining such exothermic reactions.

I Like It! _

author

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!

author

dang u are right.......sorry.plus me and godhart had the whole fire/explosive discussion already

author

yeah, i know you already had the discussion, but my comment made you learn about airbags :D

author

Tru dat!!!!!!!!!!!Well u learn something new each day.

author
Goodhart (author)sparky232008-10-16

sparklers are technically pyro(fire)technics.

:-)

author
sparky23 (author)Goodhart2008-10-17

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

author
Goodhart (author)sparky232008-10-17

they are definitely better at maiming a person *yes*

author
sparky23 (author)Goodhart2008-10-18

hmmmmmmmmm u gots to be smarter than the explosives to avoid that

author
Goodhart (author)sparky232008-10-18

even professionals get maimed now and then...some things are unpredictable...

author
cornflaker (author)Goodhart2008-10-24

But they are still more fun

author
Goodhart (author)cornflaker2008-10-24

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 ;-)

author
cornflaker (author)Goodhart2008-10-24

That sounds about right, But I'm not that old yet :D

author
Goodhart (author)cornflaker2008-11-29

Well, hopefully you are careful enough TOO become that old ;-)

author
Vulcanator (author)Goodhart2009-05-26

you mean 'to' not 'too'

author
Goodhart (author)Vulcanator2009-05-26

yes, sometimes my keyboardddddd gets carried away when I am typing ;-)

author
cornflaker (author)Goodhart2008-12-04

Haha yeah I do try to be careful still

author
sparky23 (author)cornflaker2008-12-12

nah!!!!!!carefullness is overrated!!!!!!!!!!!!u only got one life!!!!!live it man!!just live it!!!!!!!!!PEACE AND JELLO!!!!!!!!!!!

author
Goodhart (author)sparky232008-12-13

It is best to not shorten it though, if you want to truly live, you have to at least get to be an adult to find out real experiences....

author
sparky23 (author)Goodhart2008-12-17

nahhhhhhhh just skip to the good stuff at about........................14.woooooooooooooo waiting suxx!!!!!!!!!!!peace and jello

author
Goodhart (author)sparky232008-12-17

You don't have to wait you have a LOT of things to explore....it is not the destination that is the goal, it is the journey there. Enjoy the journey (since the "road block at the end of the road is not conducive to having fun" ;-)

author
sparky23 (author)Goodhart2008-12-18

hehehehehe niceeeeeeeeeeeeeee.you dont have to know were you are going provided you know who you are following.hmmmmmmmmmmmmmmmmmmmmmmm what if the anti fun road block occurs in the middle of the road before you reach the destination???or does that atomaticaly change the destination to the spot were the journey was cut short??????yes it does

author
Goodhart (author)sparky232008-12-18

What I mean is that you can have goals, but they shouldn't be absolute. The journey will be the experience you remember and gain the most from, be it knowledge or just having fun. Don't go so fast to any goal; especially aging, since that moves one closer to the last goal that no one wants to face, death.

Don't wait until you are old and wise for everything....you won't be able to do much once you are old....
