Wint-O-Green Life Savers???

Actually, all hard sugar-based candies emit some degree of light when you bite them, but most of the time, that light is very faint. This effect is called triboluminescence, which is similar to the electrical charge build-up that produces lightning, only much less grand. Triboluminescence is the emission of light resulting from something being smashed or torn. When you rip a piece of tape off the roll, it will produce a slight glow for the same reason.   
Triboluminescence occurs when molecules, in this case crystalline sugars, are crushed, forcing some electrons out of their atomic fields. These free electrons bump into nitrogen molecules in the air. When they collide, the electrons impart energy to the nitrogen molecules, causing them to vibrate. In this excited state, and in order to get rid of the excess energy, these nitrogen molecules emit light -- mostly ultraviolet (nonvisible) light, but they do emit a small amount of visible light as well. This is why all hard, sugary candies will produce a faint glow when cracked.   
But when you bite into a Wint-O-Green Life Saver, a much greater amount of visible light can be seen.   
This brighter light is produced by the wintergreen flavoring. Methyl salicylate, or oil of wintergreen, is fluorescent, meaning it absorbs light of a shorter wavelength and then emits it as light of a longer wavelength. Ultraviolet light has a shorter wavelength than visible light. So when a Wint-O-Green Life Saver is crushed between your teeth, the methyl salicylate molecules absorb the ultraviolet, shorter wavelength light produced by the excited nitrogen, and re-emit it as light of the visible spectrum, specifically as blue light -- thus the blue sparks that jump out of your mouth when you crunch on a Wint-O-Green Life Saver.  


lifesavers are definitely my favourite candy of all time.

Never heard of the stuff but is sounds awesome! :yeah:

Someone please post a video of themselves (or a sexy young girl) eating this stuff. I want to see for myself.

Fascinating ;) I just found an ebay-auction - maybe I will buy them ;)

i dunno, i dont like to drink neon-green drinks and eat glowing candybars :) my body cant take that much chemistry :)

They don’t make the kind that spark anymore? I never liked lifesavers much so I didn’t pay attention, but it still saddens me to know they’re not produced anymore :(

as far as i know they still mass produce them. i thought to look for a pack at a local store this night. i looked at the ingredients and sugar is on the package. none of the phenylalanine-sumthin stuff in them so should be good to go. :)

long time ago i tried these in a dark room, it’s not really a spark, but more of a burst of light blueish light.

haha. yeah, i remember these.

i used to choke on them so much, the mint-ness was like too powerful for my mouth, and it would leave it feeling super sore.

other than that, delicious.


tried em again, they wrok.
haven’t tried the sugarless version…

the package has a url on it too:
