Start by READING & LEARNING first!!!
A great book to begin with is ‘Dictionary & Manual of Fireworks by Weingart ‘.
“FACT: Over 95% of fireworks injuries are caused by the mis-use of fireworks! Always read labels carefully and NEVER aim fireworks in the direction of any other person! Let’s CELEBRATE SAFELY”!! “If hand-lighting your holiday fireworks, never lean any part of your body (that you would like to keep) over the direct path of the exiting effect! Always crouch low and lean over low with your ignition source to touch to the fuse”.
