Post by rockin_peach4920 »

Okay, first of all, how do glow sticks work? What affects the chemical reaction in glow sticks and what happens when the matter in glow sticks is heated or cooled?
Second, why do the glow sticks glow longer when they're cooled, and brighter when they are heated?

Thanks!!

Hello and welcome to the forums!
You can submit these questions to a search engine and get some great answers. Try it! Your second question is a great one to build a science project around. Check out the search results and see if you can come up with a problem statement and hypothesis. Have fun!
