Making glow sticks from scratch

Hi Nile Red. Dye chemist here. This is a great video but I just wanted to give some commentary about the dye concentration you used. Fluorescence is highly efficient and more concentrated solutions (even just a few mg) will self quench the fluorescence. It may seem counterintuitive, but try even less dye for more light output. Dye molecules are flat and nonpolar and will form non fluorescent aggregates at high concentrations. This is a static quenching mechanism. Dyes can also deactivate excited neighbors through collisions, so-called dynamic quenching.Colder solutions will also be brighter due to decreased thermal deactivation of the excited state. This may not be noticeable though because dye excitation in a glow stick is based on local collisions in a reaction mixture where reaction kinetics determine light output. Higher temp will give faster rates therefore more light output. I would be curious to see if you could achieve comparable brightness in a fridge with the added benefit of extending the life of the glow stick. Keep these videos coming!

I prefer radioactive materials in my glowsticks

me: "shakes a glowstick" Molecules inside it: WOW IM EXCITED

I once watched a guy drink a the content of a glowstick once at a rave party. I'm here to find out if he survived.

Me, from the yt recommendations: "ohh cool i can make glow sticks" Me, 40 seconds into the video: "oke, I can not make glow sticks"

Your voice is so nice to listen to

“nice and sTiNkY”

I watched this with my parents, and they informed me that I drank the glow part numerous times as a child and it explains a lot

Crap, now i have to cancel my glow stick video plans. hhehehe but nice work!

I love how he says "sigma" with a tired annoyance. He hates buying from sigma.

I gotta say, Nile...as the son of a chemist that worked as one for 50 yrs, you are by far the most funny and interesting chemist I’ve ever come across. This channel is amazing and you are a super ambassador for the world of chemistry. Chemists DO have a sense of humor. I recall watching Breaking Bad with my dad and he hit pause...looked at me, smiled and said...’Son, if I were a different kind of man, I could make a pile of highly pure meth that would curl peoples toes’. He’s not that guy, obviously, but everyone in the room busted out laughing because we knew it was true. You definitely get a sub and I’ll hit you up on patreon. I’ll also share this channel with pop.

I like that glow stick isn't quite perfect. It makes me appreciate how much work has gone into making them better for the market versions.

awww yea nile red getting lit with the glow sticks

please make silly string in one video

I actually made the tcpo in the lab and it's so awesome to see the compound made and utilized! Great vid!

2:35 Nile cookin up bones fr lmao

9:07 "mix it up" proceed to shake it 900 times a second

Wow, congrationlations on getting ALL THE WAY UP, Nile! You know you have ARRIVED when you're able to buy from Aldrich as an individual... 👍

The best thing about you is that you know you are a genius and brilliant but still so humble and down to earth. Kudos man.

These videos have not only taught me more than school but it’s is super relaxing. Please keep making more. Your the science goat of you tube Nile
