It is the water breaking it. The water doesnt compress so the water doesnt absorb enough of the kinetic energy fast enough so the bullet fractures. As i understand it anyway. The 50cal is travelling a lot faster so a lot more force is applied on the bigger rounds.

Later on they did a dynamite fishing one and we learned being in water when a large enough shockwave hits is VERY bad for internal organs of squishy creatures in it

It’s the surface tension that causes the shockwave, soapy water wouldn’t have the same effect.

And yes, dynamite explosives are rather more dangerous under water. Which is how torpedos work to break ships without much regard for armor.

Right so its the water that causes it to break because of the surface tension of the water.

Sounds like you are arguing against my phrasing while agreeing with what i understand. Im confused why we seem to be in a disagreement.

Maybe you can school my dumb ass though, can you eli5 what would need to happen for you to say it was the water that does the work on stopping bullets?

Dynamite in water is the same basic principle used for sea mines. History has taught us those actually work. With the bullet, it’s more about surface tension which makes sense as falling from a high enough cliff onto water if you don’t land right is nearly the same as falling onto concrete.

Cool stuff regardless and I always found their testing to be quite spot on, scientifically.
