SUMMARY

This discussion explores methods to break glass from a distance of 2-10 meters without physical contact. Key techniques mentioned include utilizing sound frequencies, thermal shock, and the concept of a controlled explosion that minimizes collateral damage. The practicality of these methods varies, with sound being deemed impractical due to equipment size, while thermal shock presents challenges in execution. The conversation highlights the need for innovative solutions that balance effectiveness and safety.

PREREQUISITES
  • Understanding of sound wave frequencies and their effects on materials
  • Knowledge of thermal shock and its impact on glass
  • Familiarity with controlled explosive techniques and their applications
  • Basic principles of physics related to force and material properties
NEXT STEPS
  • Research sound frequency applications in material science
  • Explore methods for inducing thermal shock in glass
  • Investigate non-destructive testing techniques for glass
  • Learn about controlled demolition methods and their safety protocols
USEFUL FOR

Engineers, physicists, safety professionals, and anyone interested in innovative methods for breaking glass without direct contact.

Hi

I was just wondering what ways you can smash glass without physically touching/breaking/throwing something at it. For example, I know that the "force" of an explosion can break glass that is a fair distance away from the actual explosion. So is there any way you could make something that would break glass from a distance of say, 2-10 metres that isn't a bomb, or is a bomb but doesn't cause the damage of a normal bomb, if that makes sense?

I know it's possible with sound, but it's too impractical in this scenario.

Are there any other alternatives?

The "sound" could be a frequency that humans can't hear, if "noise" is an issue, etc.

You could throw IT about 2-10 m away so it breaks itself.

You could also balance it on an ice cube, and when it melts, the glass will fall and break, etc.

A thermal shock can break glass.

Depending on the glass itself, composition, form factors, etc...there can be other options.

Thanks for the reply.

Sound is not an issue, with practcality I meant it needs to be portable, using sound would require big speakers, amps, etc.

Thermal Shock sounds interesting but it wouldn't be practical.

Is there any way to create some sort of 'explosion' that would break glass but not cause an actual explosion.. if that makes sense?

What is the application?

I've already explained haven't I?

Nope. Why do you want to break glass at a distance? Is this a window? We have a prohibition at the PF about discussing dangerous activities, and I'm trying to figure out what to do with this thread...
