if anybody has ever thought about making smoke bombs i advise you not too unless you live in a big open area, i have just made a smoke bomb today infact 10 minutes ago, i got the recipe from unitednuclear i thought this might be a bit of fun to do, so i got out the icing sugar potassium nitrate heated it ect, and i poured it in to a cardboard tube i filled it to the top, but there was some left over about 5g worth which dried quickly so i decide to light to see what it looks like and while i am doing that the other one can dry firstly small amounts of smoke are given off then alot and i mean alot, thick dense smoke, which blew back into my house( the back door was open bad mistake) setting the fire alarms of in my kitchen, the smoke travelled all the way through my dining room into the living room luckly by the time it got to my living room the smoke was about as thick as when you burn toast now then this is where my problem comes in i have about 45g of this stuff in a cardboard tube and if the 5g is anything to go by i am going to have a major problem when i light the big one, so i advise people not to make it. it would be good on halloween or paintballing ect but not for any day in the week because it will cause huge suspicion
