For the last week I've been assembling a Satchel Charge (as the parts come in) for an upcoming scenario paintball game.

It operates on about 100PSI, uses an electronically operated 3/4" anti-siphon sprinkler valve.

The Charge is fired from 2 9volt batteries connected in series on a line 20' away.

A powdered charge is put into the chamber by means of the anti-siphon connection on the valve.

The released air along with the powder fills a short and closed off section of Latex tube till it explodes.

Cleared, neat toy! Would like top see this from a distance with a huge powder load. Nicely done.....

Yea, sorry for the confusion, the compressed air pushes the powder into the sealed latex tube. The Tube is then overfilled to the point where it pops like a balloon giving a pop and dispersing the powder.

Try and get a video at a different angle, again good work.

I tried to get a video of it going off with my helmet camera but the batteries went dead. I'll try again when I get new batteries.

Got a little video uploading but its not much. I had the camera too close to the burst tube and knocked it over. It was just blast with air only.

that is awesome. i really like that u set it off from a distance. i prefer an electrically ignited powder grenade, though.

does it have enough psi to make the powder blast more dense and/or bigger? i'm thinkin that a longer piece of latex tubing would do it.

It could be made bigger by adding a larger amount of powder. The amount of powder in the test video was rather small.

can u estimate how many times more dense/bigger it can get?

I would say at least 3 times but I will need more testing to know for sure. I'll be making one later to ship off to a friend to use that will have a much bigger bang. It will be made to blow a bigger burst tube and operate with a ball valve at about 650PSI.

looks good.. you could hook it up to a remote start or an RC like singularity back in the day.

Eventually I'll pick up a few of these:

my powder grenades put out about the same. good work.

Do you use compressed air to fill a latex tube for a powder grenade?

Nicely done!
Few points/questions:
-What if the powder gets all over/in your valve and makes the diaphragm leak?
-Have you fired it without the tube? Does it make much of a difference? (besiedes acting as a burst disk)
-Can you make a vid from a larger distance?
