Sometimes the largest challenge comes in the smallest package.
These sparklers have provided a standardization conundrum like no other pyrotechnic device I have yet to try my hand at. The hardest thing to perfect is the composition itself, for which I have had to drift so far away from the original (to get even this poor result) that it is unrecognizable. Once The composition seems right, the design is touchy enough that these will still fail for me 3/4ths of the time.
Insight would be appreciated on my situation.
