Ok, Im making a movie where in the end I need to have a factory blow up. I have no budget so everything is free or very cheap. I made the modle out of foam, but now I started thinking about it and thought.... I painted the out side to look real but what about the foam inside, when it blows it will all look white. And I only have firecrakers, yeah you know those little long ones*~~~(XXXXX) <~~~awesome! Well Im also using a vhs-c camcorder so slow motion will have to be done in premier or something. So is this going to work? Or just make a big mess?  ------------------ when life's tough or dull MAKE A MOVIE!! [This message has been edited by killer_epidemic (edited 03-25-99).] |

A mess...This is not to support the use of explosives, I am VERY against it, that's why we have powder licenses.... After the fact, in the digital world, you can add a big fireball from a stock source, (Pyromania CD, etc...) and by using a little dust (Fuller's Earth) inside the model and on it's roof, you can pretty much hide flaws in the process...

I would realy realy like to do that but I dont know how! WWhhaaaaaaaa!!!!  And I totaly agree with you on the explosives but these are little firecrakers ( Ive had one blow up in my hand )they are hardly explosives. Anyways Im scared of explosives so I would never use anything I didnt think was 100% safe! ------------------ when life's tough or dull MAKE A MOVIE!! |

Killer,Well I jsut had to point out that the term "safe explosives" is a total oxymoron. And if you don't know what that means just think in terms of something akin to "good pain". Can't be good and painful unless you're a masochist or something. Anyway, stuntman is right. Use predone effects in post from a digital stock source. Whether or not you held on to a firecracker as it blew up in your hand is irrelevant. It only takes once for something to blow your hand up when you didn't expect it would. If you've had one blow up in your hand, that's nuts to begin with. But what if some smart a** at the factory said, "I think I'm going to pack this one with enough powder to blow someone's hand off and won't they be surprised". Lo and behold you'll be waving goodbye to manual dexterity with a stump. And wouldn't that be an oops? Play safe. FXMan |

By the sounds of it, your miniature won't look all that great the way you've done it. Usually they're made the same way as a real building so as when they blow it doesn't look like the walls are obscenly thick or anything. Remember scale.... this is for every part of the model. A litle trivia: in ID4, they even placed miniature furniture in the white house they blew up. Further more, just using firecrackers more than likely won't make for a spectacular explosion. I'm sorry this doesn't give much advice, but it seemed a bit flawed to me. But hey, I've been proven wrong on numerous occasions. |

If you do deside to use firworks may I sugest you go to walmart and buy a modle rocket engin pack it will come with rocket engin starters you start them with a 9vt battery buy some wires and aligator clip the wires to the starter then tuch the wires to the battery. it is much safer this way because yuo can be standing fare back when you do it. But dont do anything stupid. its not worth it to screw up your body for live.BE SAFE!!! |

I really don't think it's very wise to start taking apart model rocket engines, the danger of doing something like that should be apparent. Mike

He is not talking about the model rocket engine, he is talking about the completely safe rocket engine igniter which uses electricity to start the engine. The igniters are seperated from the engines. |

i say play it safe but if you play to safe you can't really get anything done. Maybe get some more opinions------------------

A little advice about model rocket engines. DONT EVER USE THEM FOR ANYTHING OTHER THAN MODEL ROCKETS!!! a few years ago me and some friends were drunk and were playing with the engines and a metal pipe and shooting them at things. well we got a lil too drunk and forgot to drop the engine in the pipe and lit it in front of us and it hit ME right in the arm and burned my shoulder and took a big chunk out of me. |

Well, one thing is being sloshed while playing(!) with fireworks. A completely different thing is being sober and taking lots of precautions. I think even Mike Walling would agree to that. Safety first. Christian

ok, how big is the model and what kind of foam is it made of? if you have the budget to make a few more for testing and have access to an air compressor you might want to try this.......get some ballons or non lubricated condoms, tape, baby powder and some aquarium tubing. you should be able to tape the balloon around the end of the tubing after putting some of the powder in it, hold the other end of the tubing against the air outlet on the compressor turn it on and wait a few seconds, if you have a balloon thats big enough it should inflate and finally explode, hopefully blowing apart your model, making a dust cloud and keeping you out of harms way. you can score the inside of the model with an x-acto knife to aid the balloon in doing its job and further controlling the explosion. you may need to test various types of balloons and/or condoms before you get that perfect size and stretch hope this helps

i don't know, lou, those ideas always seem alittle flawed to me. like, i would think that the balloon would inflate to the point where it would break and push apart the model before exploding. now, don't get me wrong, ive never tried it. i hope you don't take offence.------------------ movies wouldn't be movies without the SPECIAL EFFECTS!

Yes you should not drink and use explosives. I remember back in the old days doing rock shows and how much beer I spilled on the lighting panel, man only thing you could do is lick it up! Think about it how many times does this happen to you, your in the backyard setting of some illegal fireworks and you sit down your beer and some damn neighbors kid runs thru and knocks your beer over.

I'm glad to see folks using the ubb code features; yet, home-made pyrotechnic techniques like in the scooby post are just a bit too dangerous. Sorry had to edit it guys. Please don't post dangerous pyrotechnic technique on the boards please. As it was well put by stuntman be safe, be legal -- Webmaster Dale |

Ok I have some ideas too:1. Us wd40 in a squirt bottle to make some nice fireballs. Record it against a black screen, slow it down and luma it onto the clip. (This is MUCH cheaper than buying a FXcd.) 2. Use foam BOARD. It breaks fairly relisticaly. Paint the inside and outside, add furniture and use it with compressed air. You could use the blow hose on a vacume cleaner and some wd40 if you really what to blow it away. 3. Use computer 3d animation. Raydream is good at blowing stuff up. Photograph your model and apply the photos as textures to each side. I would recommend lumakeying the fire onto the scene. Don't use Raydreams fire alone it looks cheesy. Don't use fireworks. At least not the ones your talking about. They won't look like much of anything if they're that weak. Play it safe but you don't need to go over board on safety. Quick burning achohol or wd40 are pretty safe. I've gotten hit by a fire ball made from those several times. It just stings a little. Yak@u Later, Peter |

I think anyone with half a brain would know just how dumb it is to use a can of WD-40 for a fireball. And by the way it sounds you need some basic safety tips like " don't stand in the way of a flammable liquid when ignited. Mike

Do not play with fire or explosives, WD-40 can become both... it's not worth it... hospital/jail/morgue may become your options...Work smarter not harder... try to think of safe ways to get the shot... this one took 15+ years of practice, a pyrotechnican, 3 safety team members and about $600.00 worth of materials to keep it safe, if the can of WD40 goes up, I bet you won't have these things with you.. play safe, Nick |
