Ok.... Learned this a few weeks ago.
#10 sparklers doesnt matter what color, but has to be the bamboo type of stick. take two packs put them togetherin the same plastic bag that that they came out of. be careful not to break them. take one sparkler and flip it so the sparkler end is sticking out. this will be the wick. use some tape and tightly wind the tape around the sparklers. a reinforced tape works best. get everything nice and tight and your done.
Now this is best done in a open area. light the end sticking out gently set it on the ground.... then run away. should be the equivelant to a m-100 . makes a pretty good bang!!!
I am really serious, I thought it was a joke iuntil I saw it myself!!
and i still have all my fingers!!
