The Most Enchanting Firework IMHO

[@GuillotinedChemistry]

Hello to everyone visiting from NightHawkinLight and Ben's Chem Videos! Thank you so much for sharing your time with me!

[@redcastlefan]

Nighthawk is such a nice guy. I wish he would collaborate with people more. If he says you're cool, then you're cool to me. I subbed

@@GuillotinedChemistry Hey, don't sell yourself short. Everyone starts small.

[@TrowaBarton]

lets see your video next year i bet more carbon will make more sparkles

[@Nighthawkinlight]

Very good video! Sorry to have missed the premier. It's good to see you have success with homemade shoen, that's certainly the most difficult component to come by. Good job on getting all four stages also. The last stage I think you will be able to make last longer with just a little more practice in wrapping the paper. The twisting force should all come from your dominant hand on the tip of the sparkler, while your other hand's job is just to apply tension and keep the paper on the right track.

[@GuillotinedChemistry]

You are correct about my wrap! That is when I wish I had that dyed paper to help self-correct better. Thank you for the advice. I might post a video just focusing on making one. I cannot thank you enough for making your video and for sharing the Japanese documentary. It was invaluable to the progress I've made. What a gift to the rest of us and what a privilege it must have been to train at the Tsutsui Tokimasa Fireworks Company with Ryota!

[@Nighthawkinlight]

By the way, I've had success with pretty much every type of tissue paper I've tried now that I've got my rolling down. Ryota Tsutsui told me that most paper will work, but the strips need to be cut to appropriate widths to compensate for paper thickness. You will have a much harder time learning the technique if you're using fragile tissue, but the results achievable are the same once you get it right.

[@yevkob]

Thanks for the video! Awesome job. I watched your and NightHawklnLighs videos on senko henabi, made my senkos and was successful on third try after getting the right tissue paper. The tissue papper that worked for me was white (colored did not produce as good results) tissue paper that is used for stuffing gifts from dollar store or hobby lobby. Later I tried archival tissue paper which looked to me same as gift stuffing paper that I used earlier, and produced same results. Thank you guys for great videos!

[@GuillotinedChemistry]

@@yevkob I am curious to go back and try regular tissue paper to see if I can get decent results. I think it is the wrap itself, which is all important and probably does trump better paper. (that being said... if you're senko are that good with dollar store tissue paper, you should try some of the real deal!)

[@yevkob]

@@GuillotinedChemistry I bet it has to do with the wrap, from my experience same tissue paper but wrapped differently made different result

[@GoatChease]

Wow, I also used to unwind lollipop sticks. This was a very fun watch, and I love the way you speak.

[@GuillotinedChemistry]

I'm glad someone else appreciated the sidebar on lollipop sticks. I was tempted to cut that. :)

[@Michael_______]

@@GuillotinedChemistry I'm glad you didn't. I used to do that myself and think the same thing. It really is interesting how strongly things are when wound tightly by otherwise weaker materials. Kind of reminds me of the beginning scene of Ran (1985) when the shogun is giving the arrow demonstration to his sons.

If Senko Hanabi is intoxicating then, I am drunk on my butt! Started making some this morning for the first time. Made about 20 of the little buggers before I got the right composition. About another 5 and my rolling seems to be working. Not perfect but working. My drause balls are huge! Talk about on the edge... I'll be up late tonite. Video to come real soon!

[@GuillotinedChemistry]

That's exciting! Maybe I need to dust my equipment off and get back to work on them...

[@MrMTV-hg2tw]

My name is Michael Guill, it is so crazy how the universe works. I have been studying the chemistry behind these beautiful and unique fireworks for some time now. I have been toying around with different compositions and different mixtures of potassium nitrate sulfur and carbon. I have just now found out someone else with the same few letters in my name is doing the same thing. I don't know if g u i l l is your last name or not but it is so crazy that I stumbled on this channel after fooling around with these compositions myself.

[@GuillotinedChemistry]

Not my last name (actually a holdover from a much longer original name for the channel), but I'm glad you finally found your way here too that video. It is a wonderful thing to study. Welcome!

[@masonp1314]

I used to wind paper INTO popsicle sticks for fun, because I had free time... I wonder how different it is to making senko hanabi..

[@GuillotinedChemistry]

You should try making some... you'd probably a natural with that skill set!

[@scottcantdance804]

Back in 2004, after high school graduation, big group of kids from my high school went to North Carolina for beach week. People were lighting off fireworks down at the beach, and after a batch went off, guys were picking up the garbage, one of my friends picked one up that hadn't gone off, and it suddenly went off in his hand. Lost two fingers and his thumb. I was just thinking about that because of the warning at the bottom of the screen in the beginning of the video.

[@GuillotinedChemistry]

Thank you for sharing that story. Yeah, that kind of stuff terrifies me. I am probably an abnormal chemistry teacher because I think of myself as overly cautious and have a worst-case scenario mentality in the laboratory. I think that is why I gravitated to senko hanabi over all over fireworks. They are safe enough to be hand-held, and I think safer than our western stick sparklers because senko hanabi require you to be still and focused, while the stick sparklers almost beg for a more dangerous display of waving and swinging them all over the place.

[@scottcantdance804]

@@GuillotinedChemistry I'd rather work in a lab with someone who considers and plans for worst case scenarios, rather than working with someone whose attitude is "nah, it'll be fine!" Lol You seem like a cool chem teacher, thanks for your videos!!

[@GuillotinedChemistry]

@@scottcantdance804 True... I would truly regret being injured through a failure of imagination in the lab.

Hi i have watched your's and nighthawkin video too probably every main video present there for making this i have one question. senko hanabi are of 2 types paper one and some rice stick . can you please tell what is added in black powder mixture to make it a paste and how to put it on stick. i'm a student and will try this for my school project , i have to make it work in one go and i think rolling paper one would be tough as it requires practice , pls suggest something

[@GuillotinedChemistry]

I know of the rice hanabi, but they seem to be far rarer... I've never made them before. Traditional senko arent impossible to make. Honestly, you can get pretty good rolling with some practice and a lot of the videos out there. I think it's great that you're doing this for a school project. I have my students make senko Hanabi also. Hope that helped a little... Let me know how your project is progressing!

@@khushiyadav9472 Even tissue paper will work quite well... any thin paper should be good, as long as it is a tight wrap.

[@ortholux2343]

This sounded like a fun weekend project but it seems to take a little more to get working. I see the comment that sooth is hard to come by, that strange because I've been at a plant where they make tons of it. After having a 100% failure rate with grinding activated charcoal in my mixture I went to an art and craft store and bought some pure carbon black pigment aka PBk6/7 and used that in a 4 2 1 mixture. Paper used was shoebox paper. And as you'd expect this resulted in a 100% failure rate as well. With both mixtures the ball never formed and instead a hard black ghost of the paper remained. The rolled paper looked pretty good if I say myself. Was expecting this part to be much harder. And that pigment sure has a tendency to stain stuff, including the porcelain prestle. Next to a 6 3 1 ratio and different papers.

[@GuillotinedChemistry]

Try hardwood charcoal from a hardware store. It's not perfect, but it's enough to usually get it started. A 4 2 1 ratio also sounds like a good place to start. The soot is great if you can get some from work... I've spoke to some people who have access to soot from industry but it's full of impurities so it's not as useful. Yours might be different. Thank you for the progress report... I'll probably have an updated version of this video by late spring (?) 😁 Oh and it does tend to stain a mortar and pestle... I have one dedicated to it since it gets pretty blackened...

Great work! What is the weight of your Gampi paper, 9g or 12g?

[@GuillotinedChemistry]

I bought 10g. :) I would like to try some of those other two types though...

[@seiyuokamihimura5082]

Please try senko hanabi with sodium. I am interested to know if it will still act the same with using another element for colorant effects.

[@GuillotinedChemistry]

If I remember correctly, people sometimes add a little sodium bicarbonate to give it a yellow color, so you're definitely onto something. Pure sodium metal, I imagine, would be too dangerous and quite hard to work with due to it's reactivity.

[@seiyuokamihimura5082]

@@GuillotinedChemistry was what i meant, please do not do pure sodium!

[@GuillotinedChemistry]

Then we are in agreement! 😃

[@jimihenrik11]

I wonder if using fatwood (pine wood that is completely soaked in pine resin and can be found naturally) to make charcoal would result in charcoal that itself already contains pine soot. Would there be a way to test the charcoal for that? Because I have a lot of freshly sourced fatfood at home and would like to give it a try.

[@GuillotinedChemistry]

Funny you should say that! 😁 I've been experimenting with a fatwood charcoal. I think the results are promising and I think it does has more of a soot profile than regular charcoal. I think most of the KZbin shorts videos I posted used the fatwood charcoal.

[@DearDaniel3190]

Have you ever try to use furnace black instead of lampback? I'm try to figure out to ratios.

[@GuillotinedChemistry]

Do you mean soot literally collected from a furnace? Or does that mean something else?

[@bootsandboxers5079]

Is it possible to make a giant senko hanabi?

[@GuillotinedChemistry]

That's a great question and I don't know the answer. If I had to guess, I'd say no because I think a bigger dross ball would be more prone to drop off, but I wouldn't get into a bar fight over it either. :)

[@bootsandboxers5079]

The dross ball reminds me of a welding rod and how they build a ball to start there weld. So it made me think of bigger welding rods amd bigger dross balls.

[@bootsandboxers5079]

Life is an experiment! It might be worth a try. Amd i was wondering if it was possible to get color's in it.

[@Resonanttheme]

I was thinking it'd be cute if you could expand the effect in a mini cauldren pot an inch or two in diameter, dropping in bits of paper to bring about the emitting sparks. Maybe if many dross beads could be quenched somehow right after the initial deflgration, just before the sparking and gathered into a larger mass to be reheated. Then see particles of paper eaten up by the mass as you feed them to the molten cauldren. Whatever the outcome , it might be fun to contrive a method of some sort just to see if it's possible.

[@Resonanttheme]

Too, in came to mind a volume to surface area factor/oxygen might limit the size an emitting dross would support, so that any paper dropped in a cauldren of dross might be helped if impregnated with a bit of oxidizer.

[@PBnFlash]

Where did you find such thin washi paper everything I get on Amazon is super thick.

[@GuillotinedChemistry]

I ordered it from a paper company. There are a few art supply companies that specialize in paper. If you're interested I can look up the details for the one I tried. (Might be better options out there somewhere...)

[@PBnFlash]

@@GuillotinedChemistry if you wouldn't mind. The paper seems to be the main trick. I have gotten 4 different kinds of paper of of Amazon and the only one if found that kind of works is just regular art tissue paper I got at a local craft store. And it quiches the dross way too fast.

[@GuillotinedChemistry]

@@PBnFlash I ordered from the Paper Connection. I chose Usuyou Gampi White, 10g/m2. They had 24" x 36" sheets for $12.00. Again, not sure if that is the ideal paper... From the comments, it seems the wrap is way more important than the paper itself so once I get better at wrapping I might go back and try other papers to see if there is any difference.

[@PBnFlash]

@@GuillotinedChemistry ordered a few sheets :D Gonna get this by the 4th!

[@GuillotinedChemistry]

:) I might order a little variety for next time. I will say the paper is really smooth so I do struggle to start the roll, but once is is going there isn't a problem. Make sure you read NightHawkinLight's comments as he gives some advice on how to physically handle the roll based on his internship with Ryota.

The reason no one has heard of these poor excuses for sparklers is because of how lame they are. If you find these at all mesmerizing you either are using that word incorrectly, or I have to wonder about the sort of dull life you lead. If you decide to move your obsession over to a real firework type that has a projectile display with some color to it, let me know.
