What bumps certain sweet suckers into the world of blue, visible lightning is their flavoring. But we humans can’t see ultraviolet light. So far, all of this could happen with many hard, sugary candies. The nitrogen briefly absorbs the energy from the collision and then spits out some energy - in the form of ultraviolet light. In your mouth, these jumping electrons crash into nitrogen atoms, which is abundant in the air. (Recent research suggests that the sparks’ energy is powerful enough to trigger chemical reactions such as combustion.) “There is a little bolt of lightning that shoots between the faces,” says Arnold Rheingold, a professor of chemistry at the University of California, San Diego who has studied triboluminescence. The electrons leap across the gap to the more positively charged side. When you break a sugar crystal, one half of the crystal ends up with more electrons than the other. But crystals that don’t have this symmetry or are impure often do. Think: salt or diamond) Scientists believe that the structure of a crystal determines whether or not it will emit light when broken, a phenomenon dubbed triboluminescence.Ĭrystals in which every unit is symmetrically arranged around a center point don’t tend to have this feature. (Chemists define a solid crystal as a substance where each unit of matter repeats with a regular pattern. So what causes the cool light show? When you crunch down on a candy, you shatter its sugar crystals. Four tweens in their bunk beds have now independently confirmed what two minutes ago was just a rumor to us: Wint-O-Green Life Savers spark in the dark. It’s a hot night in the Adirondack mountains, crickets are playing their evening sonata and I’m watching cool-blue sparks in the dark. Turn up your sound and click on the VIDEO above to see a lifesaver sparking away.
However, the wintergreen in the Wint-O-Green Lifesavers is a special substance that absorbs ultraviolet energy and transforms it into visual light – aka triboluminescence.Is it true I can create ball lightning in my microwave oven? Eric R. This is what creates light.īut can’t I just crush a piece of sugar and see the reaction? The answer is no, but that’s just because the release of energy when regular sugar is crushed is ultraviolet light, which can’t be seen by the naked eye. When sugar is crushed with teeth or pliers, the pieces become negatively and positively charged, making electricity jump through the air between the pieces of sugar. Lightning is an electric stream that excites nitrogen molecules in the air, proving them with extra energy which is released as visual light. You’ve created a little storm in your mouth, that’s right! This actually is more similar to lightning than it is to a sparkler. What did you see? Was it a greenish-blue light? If you didn’t see the spark, repeat the experiment a few more times until you see the spark. Bite down on the Wint-O-Green with your mouth or crush it with a pair of pliers. Place the Wint-O-Green lifesaver between your teeth, make sure you are standing across from your friends or directly across from the mirror.Give your eyes 3-5 minutes to adjust to the dark, you will be able to see the spark better this way.Keep in mind you will need complete darkness to best see the spark, so if you are outdoors head to an area of your yard with the least light pollution. If you are at home with friends, you can head outside when it’s dark. Head into your bathroom and stand in front of a mirror.A pair of pliers (use if you are not allowed to crunch on hard candy).
A bag of Wint-O-Green Lifesavers (not sugarless).Fourth of July and fireworks go hand-in-hand, but you don’t have to attend a fireworks display to see a spark! That’s right, with some simple science, you can create spark (in your mouth!) with some refreshing candy.
