Hi ya i am new here and i have been in to pyro related things ever since i was about 14 i am 24 now.
I have a few questions i hope you guys dont mind me asking.
Apart from smoke pelets what else can i make with potassium nitrate?
I recently brought some potassium nitrate on ebay.
Also does the wet method of making smoke pelets work? mixing a little water and making a paste out of potassium nitrate and sugar then letting it dry and doing it that way.

I am also interested in making thermite but i am a bit concerned aobut the safty issues surrounding the aluminum powder is it safe to use aluminum powder? I have read online that aluminum powder can be a helath hazard not sure if its a myth or something but before i start buying the stuff to make it on ebay i would want to kind out first.

Last question how can i make a cherry b**b. I think they come from america but i have never actualy used/seen one only photos of them and i would love to make one.
