Does a mirror bend before it shatters? A super slow-motion video test reveals the answer.
Does a Mirror Bend Before it Breaks? Yes. - The Slow Mo Guys - YouTube
The camera used for filming was the Phantom TMX 7510 high-speed camera, which is capable of shooting at a maximum of 1.75 million frames per second.
The mirrors to be broken are as follows. For some reason,
Three large lights were provided to make it easier to identify the cracks in the mirror.
Gab from The Slow Mo Guys, clad in protective gear, smashes a mirror with a hammer.
First, check out the moment the mirror shatters in 120,000 fps slow-motion video. The hammer moves towards the mirror and hits it, making a 'thud' sound.
After that, the cracks rapidly spread in a spiderweb-like pattern. Even in footage shot at 120,000 fps, the cracks expanded in an instant.
Fragments of the mirror reflect light.
A crack slowly spreads from the center.
The visuals are so beautiful they look like they were created with CGI.
When we broke another mirror, the cracks spread in a circular pattern around the spot where the hammer hit.
The way the cracks spread depends entirely on how hard you hit the mirror with the hammer.
Next, we checked how the mirror shattered using slow-motion footage at 875,000 fps. A hammer hit the mirror.
The crack appeared not around the hammer, but from the left edge of the mirror.
It appears that cracks are extending in a circle around the hammer.
Eventually, cracks appeared in the area where the hammer had touched.
The crack suddenly widened, and it collapsed.
There was also an accident where a shard of mirror directly hit the lens of a high-speed camera.
In some cases, a crack spreads in a perfectly circular pattern from the point where the hammer touched it. The crack spreads so uniformly that it could easily be mistaken for a fictional image created with CGI.
Next, we prepared a variety of colorful lights.
Then, the colorful lights were reflected in the mirror, and it became clear how the impact from the hammer spread across the mirror's surface before any cracks formed.
You can see that the surface of the mirror is significantly curved before the cracks appear.
This is what it looked like before I hit the mirror with the hammer.
The hammer strikes, and the impact spreads across the surface of the mirror.
The impact spread throughout the entire mirror.
Then cracks appeared.
The cracks have spread throughout.
Crash
The moment the mirror shattered was filmed from directly beside it.
The hammer is driven into the mirror, but no cracks appear yet. The surface of the mirror ripples, as if the surface of a pond were filmed in slow motion.
Suddenly, cracks appeared with a 'crackling' sound.
With a 'crash' and a 'clink,' the mirror completely shattered.
It was completely destroyed.
While the still images are quite impressive, the video offers an even more dynamic experience, showcasing the spreading cracks and the sound of the mirror shattering. If you're interested, be sure to check out the video.
