How do I make a Glow Stick glow brighter or longer?
The temperature and life of a Glow Stick are inversely proportional. In other words, if you place a Glow Stick in hot (not boiling) water, the stick will glow brighter but its life will be shortened. If you place a Glow Stick in the fridge, the reaction will slow down, making the stick glow for a longer period.
