How to make a safe explosion.

I learned how to do this in a book and it works great. I've actually tried it so I messed around with the measurements of tubing and added a few extras. This works for me really well. If you film it infront of a green screen outside, you get a great explosive effect. (note: don't wear clothes that were washed with fabric softner)

1. Take a cinderblock and stand it upright.
2. Attach a funnel to te side with the funnel end up.
3. put a 4' tube connecting to the bottom (small end) of the funnel. (so it is long enough so you can be far away and can't get burned.)
4. on the cinder block right next to the funnel, put a charcoal brickette and apply a little gasoline or flamable material.
5. put high fat coffee creamer powder in the funnel (coffee mate works best) then light the brickette and let burn for 2-4 minutes.
6. Finally, step back and blow into the tube so the coffee Creamer shoots out of the funnel and lights on fire coming out of the tube for a really incredible explosion.
Then you can add an old metal gas can or a 50 gallon gasoline drum around the cinder block or set it in shallow water, for a more realstic environment. (as if the can were actually exploding)


The last time I tried it was over the summer, but wrote down the directions. Once I get a chance I will film it and post it to prove how realistic it is. Remember don't wear clothes washed with fabric softner.

If someone has posted something like this in the past tell me if you've found any better rigs please.

Because I found this in a book, I don't remember why it is a safe explosion, but I think It has to do with what is burning (coffee creamer) and how it burns so quickly so it can't catch onto anything.

For a longer explosion, put in more coffee creamer.

Although it is not 100% safe, it is more controled. It is an alternative to the very real thing (an actual explosion)

If any fire is involved, there is no such thing as "safe"; Just more precautionary tactics.

And if it works, of course it is realistic. It is the real thing.

I have an idea for a real safe explosion...

1) Use AlamDV and rotoscope some explosion stock footage onto your film.

Enjoy.

Detonation Films has had this technique listed on their site for a while as well. The reason it is safer is that the coffee ceramer only burns while airborne. If it lands on anything, it goes out.Check out this link for their illustrated instructions on how to build and use the device, as well as a video link of the effect in action so you can see the results.
