Making color changing plastic

In this video, I'll be making DNBP, which is a photochromic compound. This means that it reversibly changes in color when its exposed to UV or sunlight. Once I made it, I tried out some cool things with it, like developing photos and making a color changing plastic.

I came here to see a cool color changing bear, ended up getting a degree in chemistry.
-
This guy is just a badass. I mean, how often can you say "that's way too expensive, nevermind, I'll do it myself" Props to you!
-
I need a “but anyway” shirt in the merch store.
-
"I will update you guys when the color changes." 2 years later: Bear: Nope i just like to stay yellow
-
"In the seventh step NileRed tested the Ph, and saw that it was strongly basic, and it was good." - Synthesis 6.28.

I love that every one of your videos are ‘I’m gonna try this’. ‘I fucked up’. ‘It’s not really a big deal’. That’s literally how I live my life lolol
-
Bro... Sell your own DNBP for half price, and you're still $81.26 in profit per 50 mg. That is an insane price lol.
-
Am I the only one who doesn't understand much of this but still enjoy it?
-
I was having a bad day, then he made Science Bears and it instantly improved.
-
Brain: Eat the bear Me: wtf no it'll kill me Bear: You must!
-
I can‘t get over the fact that sigma would have sold your 2 gramms for way over 6500$
-
Instead of making bear with epoxyresine added with photo chromic dye, make bear with nornal resin and coat it with epoxy resin added with photochromic dye. Outer coat of it give fast response to light changes. Thanks
-
Went on my first university lab experience the other day. I was one of the only ones who knew how to use the fancy equipment and why we were doing things, purely because of your videos. thanks mate
-
Is it possible that the bear's reverse behavior wasn't brought directly by UV light but rather heat? You demonstrated that heat can reverse the bluing. A lot of plastic-y things absorb UV light and produce heat. Plus, that dark blue color probably doesn't allow light-triggered phenomena to propagate very quickly. So I'd wager that's what's happening here: the bear just got hot.

I have no idea, but what makes me happy is how clean his table is.
-
When I was doing Chem in HS, I never got what they wanted me to do when “observing” my procedure and write it down, thanks to you know I know EXACTLY what they mean 😂 thanks for helping my grades
-
If you add it to an epoxy that has already started to set up, you should get a suspension of crystals.
-
I really like your videos, they are high quality and great content about chemistry.
-
6:17 And the lord said "let the magnesium be pulled from the aether"

Nice to see chemistry videos! l hated chemistry in grade school! Mostly because of 'balancing equations', but as an older person ...l seem to like what you do a lot! Thanks up loader!
