Why share these clips? I think it is important to share what works and what doesn’t work. In this video, I burn about two dozen different types of washi to see if any of them really stick out for senko hanabi. Many fail, not because they are bad papers (washi is awesome), but because they just were too thick or couldn’t hold the wrap well.

This is not the final word on paper… just my results. I would encourage those with the inclination and proper pyrotechnic training to safely handle the materials to re-examine any of these papers. My results are limited by my technique and materials, so results will probably vary.
More importantly, I think it is important to always be exploring new ideas. When we commit to one possibility out of the sake of experimental control or convenience, we must not lose the uncertainty that propels discovery!
