In this video we explore a brand new process to make Senko Hanabi Sparklers, using a powder that is less flammable than the paper it's rolled in. Check out my sponsor Brilliant and get 20% off an annual membership! Brilliant.org/NightHawk

I've now organized all of my Senko Hanabi videos into one playlist: youtube.com/playlist?list=PL1a2HkcVbmAVW5LBBThCdHPD3BKDd03Tj

The title of this video makes quite a claim that I'm certain will be disputed in the comments from a perfectly literal perspective, however, flammable materials is an official classification typically reserved for things that are more flammable than ordinary objects like paper and wood. For that reason, I think calling these sparklers non-flammable is an accurate descriptor for practical purposes. Certainly they are the least flammable fireworks in the world, and the only fireworks that do not contain an oxidizing or explosive ingredient. The use of potassium bicarbonate (and sodium bicarbonate) as the primary mass of a firework composition is completely novel, and makes these very safe both to make and store compared to other fireworks.
