Watch outtakes here! http://testu.be/1grk4GC Michael Thurber of cdza joins Tara and Anthony as they attempt to break glass with the human voice. Will Michael's vocal cords be enough to get the job done? Watch to find out! Experiment Tips: - Place a straw inside the glass. When the straw starts to bounce around your voice has reached the natural frequency of the glass. - Leaded, crystal glasses work best for this experiment because they are more delicate. - A horn driver helps center the sound in one place.
