  • The glass appears to have been scored to assist/control the breakage, or it could be an engraved design.

  • It's a painted design on the exterior of the glass. We did experiment with scoring. The initial cracks would begin at the scoring but we could break them just as easily without scoring, it seems like having the right frequency is the most important variable. Our speaker couldn't break bigger glasses because the resonant frequency was too low for the speaker to produce a large enough amplitude.

  • HOW LOUD DID YOU HAVE TO PLAY THE FREQUENCY FOR IT TO BREAK? (decibels please. Oh and sorry for screaming at you, but i got your attention!)

    AND IS THE GLASS EASIER TO BREAK IF YOU RAISE THE AMPLITUDE? HOW MUCH SHOULD YOU RAISE THE AMPLITUDE?

  • i never seen anyone break a crsytal glass with sound that would be cool but the crystal is prob to thick

  • lol the straws just runs and hids

  • the glass looks... cut. is that so?

  • watch the fuqqin straw get the hell outta dodge...like it juss knew der were troubled times ahead

  • That was sweet, and whatever jam you used as the music was sweet too. What was that? Sounded a little P-Funk-esque. Maybe old Chili Peppers?

  • This is just unreal. Also, what song is that?

  • that was so cool
