    I saw a guy on tv who recorded the resonating frequency of a glass cup and then played the same frequency to break it .
    can someone enlighten me on how this is done ? The recording and the emiiting of the frequency .
    I have a good amount of basic knowledge and tools...:)
    This is just very interesting to me.
    Thanks in advance

    There was a commercial on TV many years ago featuring Aretha Franklin breaking a glass singing ... then the glass was broken again from the playback. The tape was Memorex.

    Interested in the recording and playback. When you say sound do you think this can be acheived with good sound equipment ? My brother is a DJ is it worth a shot ?
    Thanks

    It might have been a challenge for an old cassette tape recorder, but no problem for digital equipment.

    One suspects that playing a tone that destroys every empty glass in a bar may not be seen as a real yuck by the owner.

    cool link thanks cvmichael.
    I still have to convince my brother to let me try it out , he seemed a bit skeptic about it and is worrying about his copmuter screens and his windows.

    I would not worry, every object has a different frequency...

    There are examples of people using a non-amplified voice, shatter glasses on youtube.
