They are great size for me.......24" monitor!!!!  I used this recipe also. It works great. Lots of white/gray smoke, but it gets hot quick. I have also used soup cans and poured the mixture into those. Usually can get Salt Petre at drug stores. If they ask you what its for tell em that your mother/grandmother uses it on her roses. POSTED BY SteyrAUG Well first you used the wrong recipie. You don't use PN. I posted the correct recipie on the older smoke bomb thread. There is NO PN in it at all. ETA: Here is what you do... OK, here we go. The only tough ingredient is saltpetre but I imagine that is pretty simple to find in these internet days. If I could get it at 12 we can surely find it now. The most effective mix (from experiments at a 12 year old) is about FOUR PARTS SUGAR to SIX PARTS SALTPETRE. Cook it on LOW until it melts into a plastic like substance with a waxlike consistency. Do this OUTSIDE in a pan you don't want anymore. You don't want to cook this shit in your kitchen and God help you if you manage to burn it (aka light it). When it gels up nice nemove it from the heat and allow it to cool. When it cools enough to handle make your desired shapes (baseball size is good for smoke suitable for things like paintball - football size and you will smoke out a football field). As a tip when it is still maleable dump a bunch of matchheads into the mix to help keep it burning (about 12 match heads per baseball size object). And use a cannon fuse to light (I usually use about a foot of cannon fuse with 2/3 folded into the substance and 1/3 sticking out). The best method I found was to use aluminum pie tins as molds. Four the mixture into the pie tin (or cook it in the pie tin) until you have a pancake size amount about 3/4 of an inch thick. Then dump about a dozen match heads on the pancake and roll it up like a burrito (at the same time rolling 12 inches of cannon fuse inside it) Then fold the whole burrito shaped object over one time and mold it into something like a small football shape. Experiment for best size to smoke results. Enjoy. |

Saltpeter is potassium nitrate, KNO3
The drug store should have it, or a good garden store. |

That can be said of lots of things that are illegal. Why is it illegal to put dry-ice in a soda bottle? Why is it illegal to carry fire on an airplane?

It's illegal to make bottle bombs? I guess I've broken the law dozens of times. But I use HCl toilet cleaner and aluminum foil. I've also made certain high explosives, but I won't incriminate myself. Just tell the cops that it's a binary explosive (and not even an explosive.) If tannerite is legal, wouldn't this stuff be? |

Im guessing that it is legal in states that are firework friendly. Lucky for me Im in one of those states. I did not know it was illegal for the dry ice in a soda bottle. Learn someting new all the time. Well I just got back from Home Depot and they do have it. For a 1lb bottle it ran me just under $6. So I got 2 so I do not have to run back so fast. As for the pics they are not bad if you run your 17" at High Color 32 and at 1024X768 But I guess there are many here in their "Golden Age" that need theirs set at 800x600. Dont feel bad I will get there as well someday. Ill wip up a batch here and get some pics up soon.

Brings back memories.
I had a friend incinerate his kitchen while making up a bunch of that stuff. He had premixed several pounds of it and apparently was heating small quantities of it on the stove when it ignited. Needless to say the burning gunk sent sparks into the stuff he had premixed and the whole mess went off. This guy’s parents weren’t home. W got the call that he needed help and raced over. Within 30 minutes he had a dozen friends over there trying to clean up the mess. But there’s no way to hide charred cabinet doors, a badly burned countertop, or a melted coffee maker. Lessons learned… Wear eye protection and fire protective clothing. (heavy cotton, no polyester or nylon) Do this outdoors. Don’t mix up huge quantities at once and keep the premixed powder away from the burner. (It will burn just fine without heating.) Don’t heat too much at once. Rig up a double boiler and heat the mixture in that. There’s less chance of a cook off that way. |

Ready to go just waiting for the fan club to get home!
I placed the stuff inside of a toilet paper roll and packed tight. Weight is between 1/4 and 1/2 lb. Multiple fuse for faster burn. Duck taped just because I was bored! Makes it more evil looking I guess.

If you seal it up, it may actually explode, so be careful. If you just leave it in the open, it burns nice and slowly. |

ITs the one in the tube. I tested a sample so I know this will work. I live in a Hi rise condo here in Miami and I did not want to have to much smoke blowing off of the balcony. Im just waiting for the call then Im off to a friends house with camera in tow. I promise to have this up later tonight. I so just want to light and laugh.
If anyone is a camera buff I could use your help. I have a digital camera that I just got and it has manual settings on it as well as auto. Since I am going to pop this off tonight with street lights what would be a good setting to set the camera up to be able to get the best pics for this shot. I am new to the manual camera thing but I got a nice camera. Nikon Coolpix 8800. Let me know or Im just going to let it ride in Auto and hope for the best. |

It works, I was not able to get a shot of the mass smoke that it put out but there was a lot. For sure! But adding multible fuses and taping it up caused it to burn at a high rate. It was over in a matter of 10 sec.

TP roll... Come on.. I'm just waiting for one of you guys to try re-filling a spent HC White can (bonus points for an actual grenade fuse, or are those illegal?)....  P.S. for those suprised about the heat -> real smoke grenades get very hot as well... Don't shoot quite as much flame, but.... This mix seems more like an incinedrary device with smoke on the side, though... |

Yes there is. You can slow the burn rate down by adding baking soda to the mix. |

A way to slow the burn rate is to pack it down tightly, and do not confine it. It will burn nice and slowly if you pack it down.

I tested a 3/4-1 pound one a few years ago, it worked good but not as good as I planned (too much wind). The plan was for me to stand on a hill near the San Fransisco bay (about a mile away) while my friends stayed over at my house and lit it while filming it. I was going to photography the smoke cloud. Unfortunately the wind pretty much prevented this. I used this oportunity to test some new Uniden FRM/GRS radios I got. It worked fairly well, but my friend who was in charge of the filiming had an issue and didn't start filiming until it had probably burned half way. I used a 70/30 mixture, so it burned fast and hot. Here are a few pics (and some vidcaps). Keep in mind the video was taken with a digital still camera, so they aren't too good. Also, the smoke bomb was about half as big as when it started (I kept chipping pieces off and using them). The way I make them, I pack them into a mold under pressure, and the consistancy is like hard caramel. This makes them behave like a rocket engine sometimes.
     As you can see, it smoked up my street but didn't really go "up". Here was my view:   Dissapointing. Soon I am going to make some new ones. |

I'd also like to mention another experiment I did which actually did not turn out to well for me, but it made a huge amount of BLACK smoke. I took a 5 gallon water jug (the kind used in those inverted water dispensers) and cut the bottom off. I then put a rubber seal around the bottom. I put a schrader tire valve on it, and sealed the top. I sat a tub of wood chips for a smoker mixed with potassium nitrate on a piece of plywood and put the water container on top of it. I then lit it, put the cover on real fast, then used a large air compressor to pump air into the container while pressurizing it. Well, it basically exploded and made a HUGE black smoke cloud. It was pretty awesome, but I didn't think to film it since I wasn't expecting such a dramatic reaction. It really scorched the area too.

And sulfur. Mix in about 10% sulfur by weight. (you can get "flowers of sulfur" at any garden shop) Not only will it reduce the burn rate a little, it will add to the flavor of the smoke. |

You can replace the potassium nitrate with potassium chlorate with greater results.
 If you are interested in this sort of thing, take a lot of chemistry classes and read through this book: Link You really need to make sure you know the chemistry behind some of this stuff or you can really get hurt. |

But now your getting into the black powder mix. I know this is close, but are you sure. WE as kids would use 6/4/2 parts saltpetre, sulfur,charcoal (sugar/carbon base) and it would be just about that point for black powder. Sure it was fun and smelled like the 4th of July but there were times that we got lucky to still have all fingers! Drug stores sell the Flowers of Sulfur still today for about $1. We just made up a bit bigger batch and poured it over a leftover wood floor panel. It was about 10" round and about 1/4" thick. It burned much slower and put off more smoke than the one before. The can is going to be freaking crazy for sure. Violent for SURE! That one will get a super long fuse! |

So I messed around today with just a powder mixture as I didn't have a pan I was willing to ruin yet.
Even just a beer can 1/4 of the two ingredients in powder form puts off a hell of a lot of smoke and burns completely. How much better doesn't actually melting the stuff together make it? |
|

Posted: 3/8/2006 7:51:10 PM EDT

ITs about the same but you are making sure it is mixed completely when melted down. Also you can form it into what ever you want to put it in and not have to worry about the stuff going everywhere. It is violent for sure! |
