We make a glow stick that changes colour with time.

To do so, we prepare our standard chemiluminescent mixture:

10mL Diethyl Phthalate
3mg of 9,10-bis(phenylethynl)anthracene
5mg Rhodamine B
50mg TCPO
100mg sodium acetate
3mL 30% hydrogen peroxide (add last to start reaction)

First the red Rhodamine B glows and masks the 9,10-bis(phenylethynl)anthracene. But since Rhodamine B is unstable it slowly breaks down and eventually the glow stick will turn green. The whole process takes about ten minutes.

  • in this video you said sodium acetate will raise the PH

    in another video you said sodium acetate is a catalyst.

    Which is it?

  • @MrmarioRBLX Both

  • I understand what he's talking about cause of school !:D

  • @cokenotpepsi22 Yay! a school that teaches you something! for awhile there i lost hope :)

  • Might want to copyright this method, otherwise some ass fuck might sue u ಠ_ಠ

  • @MrmarioRBLX a catalyst is merely an ingredient added to speed a reaction, so its probably safe to say that anything that raises the PH and does not inhibit the other chemical's reactions it will cause the reaction to be more vigorous.

  • Hey NurdRage i read something about a chemical that when gets in contact with other chemical it changes color.

    That would not be so exciting if i didn't read it can do infinite loop where it changes from like red to yellow and back to red and then again to yellow and this continues to infinity.

  • I remember in one of my experiments during class, me and some of my classmates were exposed to one of the chemicals our teacher warned us about, within a few minutes our hand/fingers began to turn white which was the area where it was exposed on, do you know what chemical it was and why it happens? I forgot it seemed really interesting to me lol

  • @brigiey22 kmart

  • where the fuck can i get this shit??

  • This will sound stupid in most ways but, is there a way to use urine to make glowsticks?It shows up glowing under an Ultra Violet light, so why not try and make it glow?

  • so... where am i suppossed to get this stuff? target? walmart?

  • lol i just realized that his name is n. butyl lithium

  • so when it turns green is it just going to be dim like that or can you shake it to brighten it up for an extended amount of time?
