PYRO! Easy shell hit tutorial
Hey! OutcastJiob and I were playing with fire and created a realistic shell hit that can be done at home with consumer products. We filmed the resulting explosion and it will be here soon. (Can someone tell me the best codec to use? As a DV avi it is 19 mb ).
The first step is to get a small 12 or 16 fl. oz. plastic bottle that is DRY on the inside with a screw-on cap. Crush enough powder out of some fireworks to fill the bottle about half an inch on the bottom. Now take a sparkler and remove the wooden stick that you hold it with. Poke a hole in the lid of the bottle and put the sparkler in so that it extends down into the bottle but with enough poking out the top to give you time to run away. Screw the lid back onto the bottle and shake it so that the powder spreads and sticks to the walls.
Now, bury it so that the cap is below ground level but not covered in dirt.
Light it, and RUN!!! It will make a loud bang, so if you are in the UK, do it in the country or around guy fawkes night. In the US, the country or around July 4th.
If you have a blue/green screen, you can do this effect in front of it so that you can composite it into your production.

RE: PYRO! Easy shell hit tutorial
In the US, do it in a desert or miles away from people. Because people love to report explosions and you'll have a flock of angry Ambulance drivers lecturing you! Besides the fact you cannot legally buy fireworks in most states, anyway!

Or in BlakJackDavy's backyard. . . .In the US, the country or around July 4th.
Really, Epsilon? I'm in CA, and while fireworks aren't legal in my county, the next county over allows them (but you can only buy around the 4th).
Never had a problem with neighbors calling the police. . .even with the rather large boom this particular recipe makes

You'd be surprised what happens around here. Even the professionals have a tough time keeping people in line when a tiny poof goes off...OutcastJiob wrote:Never had a problem with neighbors calling the police. . .even with the rather large boom this particular recipe makes

Legally or illegally?
Legally, there are companies that sell explosive powders for firearm projectiles and/or pyrotechnics businesses. It's not as simple as click and purchase. Typically, there are background checks processed and you can only order by the lot. Explosives also require special hazmat shipping.
Illegally, well there were a couple LA black market businesses that were recently busted in the past couple months. Thousands of imported Chinese pyrotechnics were confiscated and streets had to be closed and secured. Few people have successfully house-manufactured their own soups, and sparingly have accidentally burned up themselves in the process. It's a subdued version of the underground drug trades. The only difference is, with powders you are convicted as a terrorist! Since 9-11 this method is getting trickier.
If you live in one of those wondrous places that allow fireworks, you could disassemble the items and use the powder within. It's dangerous to mess around with fireworks like this, unless you have explicit knowledge of what you are doing!

Epsilon, You sure do know your way around gunpowder
Just a question, how do you get your powder?

I don't buy powders...
I buy ammo blanks at reenactments, but that's it.

yeah, obviously you need to know what you are doing when you make one of these. I crush the powder out of fireworks, personally, but you don't need that much. The air pressure in the bottle is behind most of the force in the device. I used to live in the UK, where everything is legal (backyard bonfires? heck yes.) Bit dissapointing that there are so many restrictions here when guns are legal, lol. Anyway, I'll get the video up here as soon as I can get hosting and compress it.

Guns being legal vs fireworks being legal. . . I'll take guns
Here's the video, as promised by Davy, and posted by meee!
Clicky
First part is real-time, second part is a 350% time stretch.
I think the explosion looks pretty sweet. . . .we'll probably be using this type of effect in our upcoming war movie!
Oh, by the way. . .the little crackly sparks after the main explosion are there because I dumped the contents of some generic sparking fireworks in with the powder. In hindsight it wasn't such a great idea, but oh well.

Looks great. Besides the fact shell impacts do not really ever emit flames... I like it.

Yeah, any old fireworks will do. Davy and I have used everything from piccolo petes to ground bloom flowers to sparklers. Get enough of the powder, and just about any firework will do the job.
Hehe, yeah, fire in a shell is a bit inaccurate, but the fire is pretty minimal, considering.

Yes we have considered that, but Outcast's igniter systems are all broken right now...
About the flames - watching this in real life, you hardly see them at all, and its only really evident in the footage for a few frames. The initial fire may have been assisted by the baloon filled with air duster behind the bottle that we added just for fun. It popped early, but may have helped out a bit. After that, you see really bright flashes from the still intact lightning flash we used to set the whole thing off.
We have done one of these completely buried before, and you see even less fire than in this above-ground test.
