How I broke a wine glass with my VOICE (using science!)

  • Published on Jan 17, 2018
  • If you sing at a wine glass at its exact resonant frequency, you can break the glass without the help of a speaker! Learn the physics behind that.

    The concept of lead crystal always seemed a little off to me. Why would anyone in their right mind want lead mixed into a glass they drink out of?

    Resonate frequencies, eh? How about that EM drive? Or virtual to real photons using vibrating mirrors thanks to Dynamical Casimir Effect ( EM Drive actually that Cannae that NASA admits works after Chinese reveal theirs...)

    They can use this same concept with light and you can kill molecules of any kind even cancer cells with a resonant light frequency

    I love your channel. I think you can be a great teacher. The way you explained the concept of resonance in this video. It was amazing. can you recommend some books that are filled with fun problems?. Not just thick theory books. But books that are actually teaching physics and These books improve your critical thinking skills. Fun to read. I wish I could meet you someday.

    You need to get two bigger oscillator balls in between your legs to keep your hunger at bay . You get what I meant ?
    Resonate frequencies down there may cause you an unimaginable pleasure .

    I want to ask you something.If the sound can be lit with fire?that is, vibration is required to produce fever, and since the sound is vibration and the glass can break, can the fire be burned?please you can try it.

    You know if that guy is right about the glass getting weaker and weaker with each attempt because the defects grow more prominent each time, then you've weakened your mom's wine glasses.

    as I mentioned in your another video, Tesla said: “If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.” so, we didn't really need look much further (Hawking and others).

    why it fails easy fatigue thats why the first every jet airliner straight up imploded in mid air bc square windows and the corners build up more stress the round ones so more stress combined with the pressurization meant that small hairline fractures formed which then lead to fatigue failure and tada

    This Universe is a Hologram of pure relative motion, a time duration timing wave-package, "an oscillating system" all at once in sync, meaning that it's an elemental Superposition-point Singularity positioning system (GPSUniverse, not only Big Bang, simultaneous modulated Crunch in Black Hole recirculation = vanishing point distributed connection of modulated wave-package pulses) here-now-forever.
    No surprise that everything in it operates at a resonance? Breaking wine glasses is probably good for your health and finances.., as well as being fun.. and feeding your (universal) imagination.
    The time duration it takes to break the glass is probably an aspect of Chaos Theory analysis, like the ejection-evaporation rate of water molecules through the surface tension of the liquid, or ice crystal sublimation, and the liquid drop model of nuclear/atomic decay, Quantum Operator Fields Modulation Mechanism of probabilities in Tunneling->displacement resonances.
    Quantum Operator e-Pi-i Fields Modulation Mechanism of probabilities in potential possibilities.., the cause-effect of resonance structuring recognized in Math-Phys-Chem and Geometry in Spacetime sequences of e-Pi-i resonance imaging Holo-graphically.., is "dramatically" modeled in the Wine glass breaking exercise, and the same techniques apply in more constructive pursuits such as composing music to suit compound arrangements of instruments, performers, venues and social circumstances. The Principle In-form-ation formulae in conception, this modulation mechanism applies in the universal wave-package continuous creation connection.., "it's always now" so timing-shape compositions "flow" across the cross-sectioning Big Picture landscape in Perspective. Ie there's one Time Now, of shifting proportions reshaping according to the Observable Math-Phys-Chem and Geometry in Spacetime existence. Infinitely complex, with some limited components that are actually understandable within the boundaries of human comprehension. ., enough to know not to get carried away with fantasies +/- ?
