The science behind glow stick

What I think now (before we start) 
I think it will leak and the glow will not work and go everywhere it will spred around the table.


What I think now (after hearing others’ ideas)
Tow different chemicals come together and make it glow


What I think now (after seeing Miss C cut open the tube)
When you snap the glow stick the glass tube inside leak the chemicals. I was wrong with my perdition.


What I think now (after researching)
There are tow chemicals in the tube in the glass tube is hydrogen peroxide solution other one is phenyl oxalate ester and dye solution.


Synthesis is when start something and experiment and research to improve your knowledge.
