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!!!!!!!!!!!

    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.

    combine. %%$%$ iPhone keyboard!
