hey zero i followed your website on how to make those tin can fireballs and it didnt work the black powedered just poofed and instead of the gasoline exploding it just caught my can on fire.

How much did you use? Experimentation indicates that if the level of the gasoline in the can is above the neck of the cratermaker it usually won't ignite. Try filling the can just so the gasoline reaches the middle of the cratermaker and try that.

yeah i did use alot and the reason i made them is because i saw the fire ball on your web site and decided to make it but i filled it up all the way thanks.

zero-were on your website is this? is it the same site that is linked to krimzonpyro?

on another note-does anyone think that a gas and propane bomb would work? putting the propane-filled-baloon in between the gas and the bp in a coffee can?

i think putting the propane on top of the gas would work better than under it.

i think the gas would be ignited and propelled easier by the bp, and the propane balloon would "boost" the flame, but i dont think that the propane would help the bp's efficiency at making a gas fireball

I do not reccomend anyone do this unless the have had a lot of experience with armstrongs, becasue it is really unstable. Take a large balloon, and fill it up about 1/2 way with oxygen, and then the rest of the way up with propane. Carefully tie the balloon, and lay a sparkler right under it. Take a brick, and set it on the middle of the sparkler, and light the side with nothing over it. The brick protects the sparks from reaching the balloon, making a short fuse. When you light the sparkler, get back about 50 feet and sit down. I can swear that a 15 inch balloon will make the ground shake up to 100 feet.

That hasn't got anything to do with Armstrong's mix, but it should at the very least make a bang and a small fireball.

We used to set off trash bags full of acetylene in the dead of night. Those things made a nice little pop when they went off. All we did was fill a big lawn trashbag about halfway with air, fill the rest with acetylene from a welding rig, tie it, and shoot it with a rifle.

No, armstrongs and the oxygen/propane/acyetalene is unstable, so if you can handle armstrongs, you can hold the balloons. Especially the oxygen/acetalene balloons will set off with my air rifle, but the sounds is so fukcing loud,, way louder than a quarter stick with a 12 inch balloon, so i never want to do. It leaves nice 30 inch craters though.

i would think that the propane under the gas would work better, the bp works ignites it just fine. i guess i would just have to try it to find out.

The buffer of propane, so to speak, may prevent the fire from the black powder from igniting the gasoline when it goes off.

Propane and air isn't too horribly unstable unless it's under a lot of pressure. As noted, acetlyene is very unstable when mixed with air, and is indeed shock sensitive. It also packs about fifty times the power, so the trade-off may be worth it to you.

Yeah, that is why i said you need a lot of experience handleing armstrongs.
