I realise it is Very dangerous to mix your own powder considering the sensitivity of the substance and i am prepared to take that risk. Please tell me a proper way to mix it with good results, the amounts to use and the amount to put in a m80 tube. Thanks for your help.

You put exactly 0. grams in your M-80 tube, to be exact.
I have a suggestion, this forum is about LEGAL fireworks.
You are proposing to implicate us in a felony, for conspiracy to make
illegal explosive devices. (that is exactly what a M-80 is)
You can find "kiddie blow yourself to hell" formulas all over the net...
The quanties of chemicals that you profess to have to make your flash powder mix would equal
a huge charge... Many dynamite sticks in power.
God it scares the hell out of me.
A young person who is no longer living mixed a "couple pounds" of flash powder in K.C. Missouri, not knowing any better. He took out his neighbors too, not just himself.
Many here have suggested that you mix a gram or less, and you can see why in the demonstration that "BigBang" posted as to why this should not be attempted in the first place.
Do you know how much a gram is?
Im not being flippant... Its a very small amount.
In all honesty, I fear for you and what you might do if you were to stumble across a site like totse...
There are forums that deal with high explosives, and while the information is dangerous and should be avioided entirely, some sources are better than others.
Since you will find such sites with little effort, I cannot in good conscience not mention http://www.roguesci.org
My simple question is what cant you accomplish with BP fireworks?
Why do you have to be destructive, and engage in things that are blatantly illegal?
