SUMMARY

The faint blue light observed when peeling elastic tape in a dark room is likely due to the fluorescence of the adhesive used in the tape. When the tape is applied to surfaces like glass, it may create conditions that allow for the emission of light upon removal. Discussions suggest that the interaction between the adhesive and the surrounding oxygen could involve electron excitation, although the exact mechanisms remain poorly understood and are subject to various theoretical models.

PREREQUISITES
  • Understanding of fluorescence and its principles
  • Basic knowledge of adhesive chemistry
  • Familiarity with electron excitation and ionization processes
  • Concepts of light emission in low-light environments
NEXT STEPS
  • Research the principles of fluorescence in materials
  • Explore the chemistry of common adhesives and their components
  • Investigate electron excitation and its relation to light emission
  • Study the effects of environmental conditions on adhesive performance
USEFUL FOR

Researchers in material science, chemists studying adhesives, and anyone interested in the optical phenomena related to adhesive interactions.

if you stick elastic tape to glass or to itself, walk into a dark room, let your eyes adjust, and then peal the tape off, you see faint blue light
why does this happen?
 
Science news on Phys.org
Perhaps the glue in the tape is slightly fluorescent?

Claude.
 
I read something about a potential, oxygen in the air being broken up, and an electron jumping the gap.. but I don't get why there would be a difference in electric potential or where the energy to ionize oxygen comes from (if this is even what they meant by "broken up"...)

I tried to look up how adhesives work but apparently its a mystery, there are only models and theories (the bad kind of theories)
