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.

A full two liters of glow fluid, about as much as you would find in 100 medium sized glow sticks. Imagine going to a rave and glowsticking with a couple of these! Not the world's biggest single glow stick, but still awesome. We made this using all the same chemicals in our previous glow stick making video just scaled up by a factor of 100. The link is here: www.youtube.com Since everyone keeps asking: NO you cannot drink it, it's highly toxic, it causes cancer, liver damage and destroys your kidneys, assuming you survive the initial poisoning.

How to make TCPO or bis(2,4,6-trichlorophenyl) oxalate, used in glow stick reactions. WARNING: This procedure should only be performed by, or under the direct supervision of, an experienced chemist. Please refer to the material safety data sheets of all chemicals for their hazards. Synthesis must be performed in a fumehood. Full written procedure can be found at our website: sites.google.com The exact same process is used in glow sticks. This is NOT mountain dew. Mountain dew cannot glow like this, it does not have the crucial TCPO chemical or any chemical like that. The reaction will glow in the dark for several minutes if you use ethyl acetate as the solvent. It will glow for several hours if you use diethyl phthalate as the solvent. Thanks for watching!

How to Make a Complete and Refillable Glow Stick with a steampunk style to it. The idea is simple, use compression fittings normally used in plumbing to create a glow stick tube that can be emptied and refilled when the fluid dies. The vials or ampoules of hydrogen peroxide is created from cheap glass pipettes that are flame sealed. The other chemicals can be found from our original glow stick reaction video: www.youtube.com An important change though is the use of diethyl phthalate solvent rather than ethyl acetate. Diethyl phthalate gives a longer lasting light. Other aliphatic dialkyl phthalates can be used including diethylhexyl phthalate so you can use whatever you have onhand. If built correctly and the purity of chemicals is good then it will last 3-8 hours. If you're having problems with leaking be sure to use teflon tape. Subscribe, rate and comment! Special note: Brass is pretty hard, so if you glowstring with this and hit someone... it's going to HURT... so be careful! Our website at: www.nurdrage.com

Dr. Arnab Bhattacharya (TIFR) demonstrates the Traffic-lights and TCPO-Chemiluminescence reactions at The Fergusson College Chemistry Club, Pune. Traffic lights reaction : Pour about 150 mL of 0.1 M dextrose into a bottle. Add 6 mL of 3 M NaOH solution and 4-5 mL of indigo carmine solution. This should be done about 30 minutes before the demonstration is to be used. The color of the solution will gradually change and become yellow. When the solution is shaken gently it will turn back to green or a light blue. This cycle can be repeated many times. After a while the indicator seems to "wear out". When this happens add more indigo carmine to enhance the color changes. TCPO-Chemiluminescence : mix together - 10mL Diethyl Phthalate (solvent) 3mg of fluorescent dye (9,10-bis(phenylethynyl)anthracene for green, Rubrene for yellow, 9,10-diphenylanthracene for blue, and rhodamine B for red.) 50mg TCPO (Bis-2,4,6-(trichlorophenyl)oxalate) 100mg sodium acetate 3mL 30% hydrogen peroxide (add last to start reaction)

We show how to make glow sticks and go through all the chemicals needed as well as how to make different colors. We also talk about the chemistry and scientifically research a proposed mechanism. To make the glow stick mix together the following: 10mL Diethyl Phthalate (solvent) 3mg of fluorescent dye (see below) 50mg TCPO (see below) 100mg sodium acetate 3mL 30% hydrogen peroxide (add last to start reaction) The fluorescent dye can be 9,10-bis(phenylethynyl)anthracene for green, Rubrene for yellow, 9,10-diphenylanthracene for blue, and rhodamine B for red. TCPO is expensive to buy but can be made for much cheaper by following the directions in our previous video: www.youtube.com The chemicals, including the ones to make TCPO were purchased from alfa aesar: www.alfa.com The Rhodamine B and Rubrene dyes were instead purchased from sigma Aldrich www.sigmaaldrich.com The dyes and TCPO are carcinogenic and gloves should be worn when handling them. The TCPO and sodium acetate amounts can be varied considerably and still obtain good light. Smaller quantities tend to be dimmer and decay faster, while larger quantities last longer. For those of you higher level individuals that actually do want to know the mechanism for this process, please refer to this article: pubs.acs.org

I had some cardboard tubes lying around, (the kind that come with confetti in them) and I decided to have some fun. I put a small explosive in the base of the tube, taped it in place, and buried that end. Then I just dropped a bundle of cyalumes on top and set it off! the first one blew through the tape and didn't work very well. I reinforced the second one and it worked much better. The glowsticks are a little hard to see, but I estimate that they reached roughly 50'. Enjoy!
