How many pieces of glass can a fired bullet penetrate? A shocking movie captured with a high-speed camera

The Slow Mo Guys , who has released a super slow motion image that captures the moment when the glass breaks and the bullet of the rifle flying from the front with a high speed camera, said, 'How many thin glasses do you need to stop the bullet? I posted a movie that verified 'Can you do it?' You can see how the bullet penetrates the glass and destroys it, and how the thin glass stops the bullet in a powerful slow video.

The two people who conducted this experiment were Gavin (left) and Daniel (right) from The Slow Mo Guys.

The bullet used is 9 mm, and the glass is as thin as 1/8 inch (about 3.17 mm).

We also use the

Phantom TMX 7510 high-speed camera, which can shoot at speeds of up to 1.75 million frames per second. Now observe how the bullet penetrates the glass, how it travels, and at what glass it stops.

First, when three pieces of glass were placed experimentally and a bullet was fired, the first piece of glass was torn into two cleanly from where the bullet hit, and the second piece of glass was beautiful as shown in the image below. The glass was still standing, although a hole was opened and part of it collapsed due to the impact.

The image below shows what was captured by a high-speed camera. After penetrating the first piece of glass, the bullet collides with the next piece of glass while wearing a piece of glass. Here, the bullets appear to be slowing down after penetrating the first piece of glass, albeit slightly.

If you do the same shot with 10 pieces of glass that are closer together, the bullet will pierce all the glass vigorously ...

The glass shatters so that it pops after a short delay. At this time, you can see that the bullet is clearly slowing down every time it penetrates the glass.

'If you slow down this way, you shouldn't be able to penetrate 20 pieces,' he said, placing 20 pieces of 1/8 inch glass on a 6-foot (about 1.8 meters) table. We experimented with 'how many pieces of glass can a bullet penetrate?' And fired it at the glass in order to take a picture of it with a high-speed camera.

Then, all the glass did not shatter, and some of it remained.

Looking at the bullets advancing with a high-speed camera, after penetrating 11 pieces of glass ...

Momentum has stopped to catch the broken glass pieces on the 12th piece of glass. As you can see from the broken glass, the range of impact that the bullet penetrates and spreads gradually expands from the first piece, and it seems that it diffuses completely at the 12th piece and only shakes the glass slightly.

The bullets picked up from the surrounding area were crushed by Pechanko.

In order to verify 'Will the exact same number of glasses break if I go again under the same conditions?', I installed a

GoPro camera behind the 12th glass and took a picture. The movie that instantly shatters to the glass in front of you is a masterpiece.

As a result, the glass just before installing the GoPro broke cleanly, and the bullet penetrated the same 11 pieces of glass. According to Mr. Gavin, there may be cases where the crushed and scattered pieces of glass break up to the 12th glass due to the impact, but it is thought that the bullet itself completely loses momentum and stops when it penetrates 11 pieces. ..

When I look at the high-speed camera focusing on the 9th to 12th shots where the bullet's momentum weakens and stops, the bullet clearly slows down and pushes forward ...
