Shattering glass is one of the classic subjects to film in slow motion. But with their recent video, Gavin of the Slow Mo Guys takes it to the extreme. He plays “a wine glass’s least favorite sound,” cranks up the volume until the glass shatters, and films it all at the staggering 187,500fps.
The Slow Mo Guys did a similar experiment five years ago, shooting at 343,915fps. Apparently, this time you can see the glass breaking at a much slower pace. Precisely, “around 7500x slower than you can see with your own face,” as Gavin explains.
For this attempt, Gavin uses the Phantom TMX 7510 at 187,500fps and a few wine glasses. He backlights each of them, and adds a speaker in front of them with a piece of a PVC pipe to focus the sound on the glass. He uses a piece of paper to see when he’s approaching the right frequency. The paper vibrates when it happens so he knows that he’s getting there, and all of the glasses resonate at around 505 Hz.
One of the glasses blows out the speaker before blowing up itself. You can even see the smoke around five minutes into the video. So, Gavin replaces the coil in the speaker, and eventually, even this stubborn glass had to give in. One of the glasses is filled with water, which looks magical when it starts resonating. Gavin also moves two glasses down a bit to make the sound closer to the rim. Each time, he films the result and plays it back much slower. And even though I’ve seen glass breaking in slow motion dozens of times – it’s still fun.
The video ends when Gavin blows up the speaker again. But thankfully, he’s already captured lots of footage so there are enough fun sequences to watch.

Interesting fact about the world trade centres..
With miles of steel train tracks and tunnels for the subway system underneath the buildings..
Cost cutting measures that prevent them from using the best earthquake pads..
Design flaws that had the buildings reengineered while under construction because they suede too much in the wind…
One theory nobody’s ever been willing to investigate is whether the shotty construction industry which was riddled with corruption and organize crime was the actual cause of the buildings collapse.
There is no doubt that terrorists hijacking the planes and flying them into the buildings what is the cause of the buildings collapsing..
Because the planes push the buildings into motion and caused them to sway back-and-forth like a pendulum.. The lack of earthquake pads allowed the foundations of these buildings to transfer that energy to the ground is vibration.
This vibration was transferred through the metal tracks in the hollow tunnels which then became echo chambers and allowed reverberation to transmit vibration back to the foundations of the building.
These vibrations travelled up to steal skeletons of the reengineered inner structure of the buildings.
As the momentum of the swaying buildings started to diminish the frequencies changed.
Once the vibration and frequency hit the right frequency just like what you see with those glasses and what Nikolai Tesla proved with his earthquake machine…
The residence frequency started blasting the rivets out of the steel girders from the inside of the building causing what looked like a controlled demolition of the buildings.
In other words the city of New York and it’s contractors built a building that would’ve come down in High enough winds even if terrorists have not flown airplanes into the buildings.
If they had used the same kind of earthquake pads the Japanese use the buildings wouldn’t of collapsed. If they had halted construction when they realized the structure swayed too much rather than trying to re-engineer a partially built building those buildings would’ve withstood the airplane attack.
The only real cover-up in that situation was that those buildings were destined to come down one way or another. it just happened to be a terrorist attack it took them out.
