it's still glowing after 5 hours. I remembered once upon a time I got several glow sticks. I was excited just like today, but soon, my interest moved to other things (what do you expect when I was a kid? Focus on something for hours? No one paid me to do that), and when I suddenly realized, the glow sticks died and no longer glowed.
I think that might be the first time in my life that I felt the emotions of experiencing the end of something. This week I bought glow sticks purely because I suddenly remember my cousin's kid was playing with that several weeks ago. So by pure curiosity, I was thinking maybe a powerful glow sticks can be used as emergency light? After all, the power outage is pretty common in my area.
Never thought a glow stick would bring out that much of emotions : )
