How Many Glass Panes Will a Bullet Go Through? – The Slow Mo Guys



Gav and Dan slow time down by 4000x to see the exact moment a 9mm bullet can’t go any further through multiple panes of glass. Instagram – https://www.instagram.com/theslowmoguys

  1. One thing they didn't mention, which I thought was really interesting, is how the bullet only deformed/broke up after it had lost most of its energy and was traveling far more slowly. That's not what I would've expected at all.

    Also, it would be interesting to see what if any difference there would be with the panes stacked closer together or further away. Sometimes you can see the next pane flexing as shards hit it from the previous one, ahead of the bullet. I'm wondering if, at certain distances, the bullet is hitting the pane while it's flexing towards it, which would make it harder for the bullet to break it. If that's right then at different distances between the panes, the bullet may be hit a pane as it's flexing away from it and therefore be more able to break it.

  2. now the question – does it matter how close the panes are together? does the number of panes need to change if they're closer or further apart?
