Wintergreen candy sparks and citrus fruit batteries

Lightning in Your Mouth

Materials

A roll of LifeSavers (Wintergreen flavor)

A dark room

A Mirror

I turned off the lights, unwrapped the Lifesavers and watched myself in the mirror as I bit into one.

Observations

As the title of the lab suggests, I saw tiny sparks coming from my mouth.

Crushing sugar creates electrical fields, which, when they recombine with their electrons, emit waves of blue, violet, and invisible ultraviolet light ("Lighting in your mouth," 2015). This particular brand of candy (all candy contains sugar) is special because "Wintergreen oil converts ultraviolet light into visible blue light, making the light you can see brighter" ("Lighting in your mouth," 2015).
