A very long trail of various powders lit to show the difference in burn-characteristics. Your guess is as good as mine how long it is. I believe they said it cost over $1000 to create this exhibition. Smokeless powder, flash powder, black powder and some sort of sugar-based explosives were used. This was done at the explosives demonstration I filmed back in May 2012. If you are a fan of slow motion flaming things, you will enjoy this.
