Discussion Overview

The discussion centers around the phenomenon of glasses and lightbulbs spontaneously exploding on a user's desk, specifically in the context of their placement between a computer screen and speakers. Participants explore potential causes, including environmental factors and physical properties of the objects involved.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant reports that glasses and lightbulbs have exploded without any apparent mechanical stress or temperature extremes.
  • Another participant inquires about the presence of water or music, suggesting these could be contributing factors.
  • A later reply emphasizes the need for more specific details about the incidents to form a theory.
  • Some participants mention the possibility of ultrasonic vibrations from the monitor affecting the glass, while others question the likelihood of resonance being the cause.
  • Concerns are raised about the physical properties of the glass and lightbulbs, including whether they are tempered or the thickness of the glass.
  • One participant suggests that there may be a grain of sand causing scratches that could lead to breakage.
  • Another proposes conducting experiments to test various conditions to identify the cause of the explosions.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the potential causes of the explosions, including environmental factors, physical properties of the glass, and the influence of ultrasonic vibrations. No consensus has been reached on a definitive explanation.

Contextual Notes

Some participants note the lack of detailed information about the incidents, such as the specific type of glass and the conditions under which the explosions occurred. There are also unresolved questions about the role of the monitor and other potential sources of vibrations.

lol its an LED.

but funny, i actually got it repaired a month ago.. because of power failure..

ist this 'leaking frequency' a health hazard?

Maybe—if you're a bat. :-p

Quick question: You are all assuming that michojek uses a CRT monitor? They are quite rare today.

Delaminated transformers make high pitched noises. Eventually ultra sound? Might there be one in the speakers or even in a non-CRT monitor? But quite frankly I doubt this could cause glass to break.

Ferrite cores as used in high-frequency switching power supplies exhibit magnetostriction, so can be a generator of high-pitched sound.

How often did this happen?
