Glass Break
How can you break glass with sound ?
I am doing a Physics project for my class and I want to Break a wine glass using a perfect C . Do you all know of how I can do that ?
It is not easy to break glasses sonically, but I have heard reliable reports that is has been done.
You need to "ping" the glass, and measure the frequency of the resulting vibration. This gives you the most significant harmonic of the resonant (natural) frequency.
This is best done with a microphone and a frequency analyzer. If you are a musician, you may be able to get close enough by trying different notes and comparing them by ear.
Then, you need a big speaker making just this frequency. Put the glass in front, and let her rip!
I expect you'll have trouble getting one to break. If so, try different glasses, some are easier to break than others.

| | Break the Glass (Paperback) $20.99 "As elliptical and demanding as Emily Dickinson, Valentine consistently rewards the reader."—Library JournalIn her eleventh collection—honored as a finalist for the Pulitzer Prize in poetry—Jean Valentine characteristically weds a moral imperative to imaginative and linguistic leaps and bounds. Whether writing elegies, meditations on aging, or an extended homage to Lucy, the earliest known hominid, the pared-down compactness of her tone and vision reveals a singular voice in American poetry. As Adrienne Rich has said of Valentine`s work, "This is a poetry of the highest order, because it lets us into spaces and meanings we couldn`t approach in any other way."From "If a Person Visits Someone in a Dream, in Some Cultures the Dreamer Thanks Them":At a hotel in another star. The rooms were cold anddamp, we were both at the desk at midnight asking ifthey had any heaters. They had one heater. You areill, please you take it. Thank you for visiting my dream.*Can you breathe all right?Break the glass shoutbreak the glass force the roombreak the thread Openthe music behind the glass . . . Jean Valentine, a former State Poet of New York, earned a National Book Award, the Wallace Stevens Award, and the Shelley Memorial Prize. She has taught at Sarah Lawrence, New York University, and Columbia University. She lives in the Morningside Heights neighborhood of New York City. |

Sony Vegas Tutorial - Glass Break Intro
if you put a glass in the freezer, halfway full with lukewarm water, will the glass break when water freezes?
i'm quite certain that the glass would break, but it'd be great if someone could give me a definitive answer as to why the glass would break. or, should i be wrong, someone give me details as to why i'm actually wrong.
yes the glass would break because unlike any other liquid water expands when frozen therefore the glass would break regardless of how full it is
