Today we take a closer look at a video we posted a while ago. In this video we have pushed in to put you right at the center of the explosion. There is enough detail to actually watch the vectors of the fluid movement.
Materials
We can skip this, if you don’t know how to make this already, you don’t need to be making it.
Procedure
Detonate using electronic detonation.
Result
This is a crop of the previous video found here. This puts you right in the center of the raging fireball. You can see the movement of the fireball fairly clearly in this video. It is interesting to note how the flames move and evolve. At speeds like this you really get a chance to see things that are ordinarily invisible to the eye, the motion and formation of the fireball being one of those things.
This is a close up of a shot we had filmed a few months ago.
Materials
Right around 1/4 gallon of gasoline.
A video appropriately titled “Fire and things not to do with it because you might lose all the hair, and skin, on your body.”
Procedure
Let’s not and say we did.
Result
This close up shot allows us to take a little closer look at the previous video, giving us some more detail to work with. This video shows the point where the gasoline has completed its burn and is now turning to smoke. This is a great look at one of the things I think is prettiest about this shot. The fire itself is pretty, the smoke is as well, but both of them together make for that classic fireball we all know and love as made popular by countless action flicks. I especially like the way the smoke takes the light, it really gives you a feel of how dense the smoke actually is.
This is another clip from the series we shot for the KillSwitch Engage video.
Observations
This is another really good opportunity to study the dynamics of fire. The flame in this instance was again caused by igniting gunpowder misted with kerosene. The previous posts on this topic really sighted everything that needed to be pointed out, but it is awfully neat to watch another version of it. Well it is if you happen to be interested in the dynamics of fire.
Today we have another bit of fire from the video below.
Observations
This is a nice crop of some very violent flame. This flame was over 8ft tall and lasted no more than about 4s. There really isn’t much to be said about this fire other than that it is incredibly pretty. The motion is fun to watch, the way it rolls over and around the top of the window frame.
Today I finally get to show you the project I was referencing with the flaming window shots. This is the video for “The arms of sorrow” by Killswitch Engage. The flames were used in that little segment with the firefighter. That was our only part in this video, but the rest of the video is a good showcase of slow motion footage. Special thanks to Eric, Nick, Brandon, and Matt for their assistance with the shots.

Materials
A wood framework window.
Black tin-foil (from FilmTools)
Gun powder
Kerosene
Procedure
This was a fun shot to make. We first built the framework and the flu to guide the fire. We then filled a small metal bowl (about 12″ in diameter) with 1/2lb of gun powder and misted it with kerosene to slow the reaction down. We also sprayed the sides of the enclosure with kerosene to leave give the impression that the fire was burning the wood frame.
Observations
This was an absolute blast for us to film. We don’t often get people asking us to do specific shots for them so this was especially fun for us, not only did we get to make something for a really nice music video but we got a chance to do a bit nicer setup than we ordinarily do (this happens when you have a budget). This video is a prime example of what slow motion filming is good for as it pertains to entertainment. Most of this video was filmed with a Phantom high-speed camera. Sadly, I myself have not yet had the opportunity to film with a Phantom camera but I hope that will eventually change. There are so many things that can be observed in this video that I will leave it up to the viewer to decide what is worth observing.
Today we take a closer look at the previously posted flaming line of gun powder.
Materials
Coarse grade gun powder.
Procedure
Lay the gun powder out on a burn resistant surface, ignite it.
Results
The fire starts at one end and flares across the width of the line and proceeds to roll across to the other end.
Observations
This is absolutely fascinating. The previous shot was interesting but being closer in on this shot really allows us to get a good look at the sparks. I find the sparks to be one of the most interesting parts of this shot. The motion that stands out most to me is the wiggling and swirling, the way the flame conforms to the motion path is neat. I slowed this one down 25% of normal.
This is another shot from that as of yet unnamed project.
Observations
There isn’t much to say about this that can’t be seen. The difference in color from the sides and the primary flame comes from a difference in fuel, the main flame is fueled by gun powder, the sides have been sprayed with kerosene.
