Homemade Senko Hanabi Sparklers

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.

how do you make thoese

[Nighthawkinlight]

A guide is on my to do list for the somewhat near future..

[emitman85]

@Nighthawkinlight

exactly how far in the future?

[Nighthawkinlight]

@emitman85 Further than I intended. I have experimented many times with these and am yet to find a way to make them simple enough to make a tutorial.

@Nighthawkinlight 2years later.. Is there a tutorial yet? Please reply

[Nighthawkinlight]

@Heliman96 No, I've forgotten about them. I put weeks of work into trying to make them consistent enough for a video and never figured it out. I may try again in the coming months.

i was able to buy some commercially made ones. ive found you need a really steady hand for these to work right

i just saw these in Yankee-Kun & Megane-Chan and thought.. what the hell is the bulb on the end... and now i know.

I have made these before with a somewhat reliable success rate and I have found that extremely fine hardwood charcoal works well for longer sparks. Hope I help, cheers.

Check out the senko's I made by searching on this site for 'gemini senko hanabi'. I was able to make this standardized device work 5 times in a row! And with pine-soot sparks!

I actually read that they are much more reliable when using realgar, but who wants to risk their health to make and burn a few sparklers?!? I mean, If it were an ariel shell, that's one thing... but I'd rather not risk my lungs to arsenic poisoning just to see a few sparks. Still, I read that when they DO work perfectly, They are reguarded as one of the most beautiful sparklers in the world...
