Over Easter weekend I worked on many projects.... while building the base for a large treehouse, I threw a toy together for my brothers to play with. Essentially, it is just a 2" x 60" pvc pneumatic chamber with a simple ball valve that is tied into a 4" x 18" steel sch 10 pipe. Fill the 4" pipe up with sawdust, put a bit of gas on the top, light it on fire and let the air loose. The more sawdust and corresponding amounts of air, the larger the fireball.[youtube][/youtube]

nice:)

i have to try that !

Looks fun! I bet it is hot for whoever shoots it.

wow, that sh*t is crazy! gotta try that sometime....

Hahah its nice
But I think the guy firering the gun is in danger of getting burning stuff all over him.
I wouldnt want to do it that way.

Thats freakin awesome. I gotta give you a hand on that. Unfortunately I think that might be against some of the rules of the forum. I dont wanna look it up right now about flaming projectiles, just dont be suprised if this gets locked.

Basically saw dust a form of very low grade of explosive so it doesn't surprise me...you'd get even better results if you used a flour...

Or coffee creamer!

woah thats nice ... a bit sketchy for the guy who shoots it though...

I have eight 5-gallon buckets full of sawdust flour- very very fine sawdust that I will use later this spring and closer to dark so that you can see it better.

I got video no longer available.

thats pretty wicked we do it with plastic bottles and fill them will a lil gas light it a step on it lol
