You bend it until you hear a tiny, satisfying *snap*, give it a shake, and suddenly it blazes with an eerie green light. No flame, no battery, no bulbjust a stick of soft light in your hand. This is chemiluminescence, which simply means \"light made by chemistry,\" and it is one of the few ways in the world to make light that gives off almost no heat. Unlike a candle or a light bulb, a glow stick stays cool enough to hold all night long.  \nThat coolness is exactly what makes a glow stick so clever, and it starts  \nwith what's hidden inside. Before you snap it, the tube holds two separate chemicals: a liquid mixture sitting in the plastic, and a fragile glass vial floating inside that liquid. When you bend the stick, the glass breaks and the two chemicals finally meet and react. The reaction rearranges the molecules and releases energybut instead of escaping as heat, that energy is handed to a dye molecule, which promptly gives it off as visible light. Change the dye and you change the color, which is why the same basic reaction can glow green, pink, orange, or blue.  \nBecause that light comes from a chemical reaction, its speed obeys the same rules as any other reaction, and temperature is the biggest rule of all. Have you ever noticed a glow stick fading fast in warm hands or lasting longer in the cold? Heat makes molecules move faster and collide more often, so a warm glow stick burns brilliantly but exhausts its chemicals quickly. Cold slows those collisions, so a stick left in the freezer glows dimly but can keep going for many extra hours. In other words, you can trade brightness for time-a bright, short show or a faint, long one, depending on the temperature.  \nTrading energy back and forth is also the secret behind a very different kind of glow you may own: glow-in-the-dark stars stuck to your ceiling. Those stars use phosphorescence, not chemiluminescence, and the distinction matters. A glow stick makes its own energy by mixing chemicals, but a plastic star makes no energy at all- it only stores light it already absorbed. Hold it under a lamp and its atoms soak up energy, then release it slowly as a greenish glow for minutes after you flip the switch off. That is why the stars fade by morning and need a fresh dose of light before the next night's show, while a spent glow stick is simply done.  \nBoth tricks depend on special glowing materials, and one of the most common is a compound called strontium aluminate. This modern phosphor, which came into wide use in the 1990s, can glow for hours and vastly outshines the older zinc-based paints that faded within minutes. You'll find such phosphors in watch hands, exit signs, toy stars, and the swirls painted on Halloween costumes. Not every glowing safety product works this way, though, and the difference is worth knowing on a dark street. Reflective tape on a trick-ortreater's bag makes no light of its own; it simply bounces a car's headlights straight back at the driver, which is why it seems to flash to life only when a car approaches.  \nThat last point is more than trivia- it may be the most useful science on this whole page. A glowing  \nstick helps you see the sidewalk, but it does almost nothing to help a driver see you, because its light is too faint to travel far. Reflective tape, by contrast, throws a driver's own bright beams back at full strength, turning you into a bright signal from far down the block. So the safest costume pairs both: chemistry you can carry and physics that answers the headlights. The next time you snap a glow stick and watch it flare, remember you're holding a tiny, cold chemical fire-a flame that will never burn you.  \nHow Glow Sticks Glow  \nName:  \n\n| Solve each problem.\u003Cbr>Use the article to answer the question.\u003Cbr>1) According to the passage, what makes glow-stick light unusual compared to a candle or light bulb?\u003Cbr>A.
