I wonder if being in a bigger body of water would make it safter Since then the force wont bounce back and crush you

[@andrewcharles459]

The division of the surface of the grenade into blocks was primarily to enhance the user's grip. It was HOPED, as a side-effect, that it would also enhance fragmentation, providing a more even distribution, but this did not turn out to be the case in practice. The casings are rough cast and quite uneven internally, and the production of fragments was inconsistent.

The idea makes a lot of sense, but also to consider. The human body has a lot more mass between the air cavities and the force of the water than a balloon does. Our body wouldn't rely on the air inside to keep it's shape, we have a little something called bones. I think it would be helpful to see how much damage the shockwaves like that would do to bone and muscle, instead of just air and rubber.

[@bastion8804]

Not safe. You're more likely to lose your leg. While grenades have a designed time to go off (varies depending on the grenade), it usually explodes earlier than that. By kicking the grenade, you're taking the chance that it won't explode until it's already a few meters underwater.

[@k1ngtempest]

[@mati865]

If the grenade is on the land then jumping into the pool would be much safer. As mentioned in the video, air between the grenade and the pool is compressible so the blast wave going through the water would be too weak to hurt you.

Human bodies are actually pretty resistant to shockwaves we can survive being blasted by an over pressure wave of 20 to 40 psi. That is within a nuclear bombs severe destruction zone! The danger from the blast wave lies more with being thrown into solid objects from the blast/resulting winds or objects being thrown into you(that is aside from the thermal and ionizing radiation issues the one will also have to consider ofc).

I guess he used that phrase, because he explains things so almost everybody can understand. So it makes sense that he doesn't use strict scientific terms at all times, because sometimes they are not needed to explain something and they make the overall message more noisy

but how far away from the grenade would you have to be to be safe underwater? I mean there's just some instances where you have no choice.
