With one satisfying snap, a plain plastic tube bursts into color that can last for hours, and it does it all without a single spark of fire. Firefighters, deep-sea divers, and trick-or-treaters have all relied on this trick, because the light is completely cold to the touch. How can something shine so brightly yet stay cool enough to hold in your hand? The answer is a chemical reaction hiding inside that skinny plastic tube.  \nThat cool glow comes from a process scientists call chemiluminescence, which simply means \"light from chemistry. \" Inside every glow stick, a thin glass  \nvial floats in a liquid, keeping two chemicals apart until you are ready. When you bend the stick, you shatter that glass and let the two liquids finally meet and react. The reaction releases energy, but instead of escaping as heat like a flame does, almost all of it leaves as visible light. A dye mixed into the liquid decides whether you see green, blue, pink, or orange.  \nBecause it runs on chemistry rather than heat, this reaction obeys the same rules as chemistry class. Have you ever noticed that a glow stick fades fast in the summer but seems to last forever in the fridge? Warmth speeds the reaction up, so the stick burns brighter but wears out sooner, like a candle with a bigger flame. Cold slows the reaction down, dimming the glow while stretching it out over a much longer time. Some campers even freeze old glow sticks overnight to squeeze a little more light out of them the next day.  \nThat fading race between brightness and time is one reason glow-in-the-dark toys work in a completely different way. Instead of mixing chemicals, they use a phosphorescent powder that soaks up light and stores it like a tiny battery. Hold a plastic star up to a lamp for a minute, then flick off the switch, and it keeps shining because it is slowly releasing the light it absorbed. Many of these toys contain a compound called strontium aluminate, which can glow for hours after just a short charge. Unlike a glow stick, a phosphorescent toy can be recharged again and again, as long as there is light to feed it.  \nStoring light is clever, but bouncing it back is what actually keeps trick-or-treaters safe on dark streets. Reflective tape and strips do not glow on their own at all; instead, they hurl a car's headlights straight back toward the driver's eyes. Tiny glass beads or angled mirrors inside the tape send the light back the way it came, so a costume seems to light up the instant a car approaches. Safety experts often suggest adding reflective strips or a glow stick to dark costumes for exactly this reason. A single strip of tape can make a walker visible from far enough away to give a driver time to slow down.  \nFrom reactions to reflections, all these tricks share one surprising goal: making light behave the way we want it to. A glow stick spends its energy in a single burst, a phosphorescent toy hoards light and doles it out slowly, and reflective tape simply refuses to keep any light at all. Firefly light works much like a glow stick's, using chemistry to shine without heat, which is why some people call the effect \"living light. \"Scientists have even borrowed these ideas to design glowing markers for medicine and safety gear worn by  \nroad crews. So the next time you snap a glow stick on Halloween, remember you are holding a controlled chemical reaction cool enough to wear around your neck.  \nHow Glow Sticks Glow  \nName:  \n\n| Solve each problem.\u003Cbr>Use the article to answer the question.\u003Cbr>1) According to the passage, why can a glowing tube be held safely in your hand?\u003Cbr>A.
