I heard somewhere at a really young age that glowsticks will keep glowing the next day if you keep them in the freezer after you “snap” them and they are still glowing overnight.
I’ve done it many times, including last night for the kids, and it always works. They won’t glow right away until they warm up, but if you leave one out overnight it’s always dead.
TL;DR – Why does cold put glowstick fluid in a stasis-like state?

The light is caused by a chemical reaction that happens when the two liquids mix
Cooling them down slows or even stops this reaction
