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.
Who cares if your body keeps it shape n structure if those balloons represent your organs
Must try this out on a ballistic dummy
Saw this video 6 years ago and now I forgot that mark was apart of this experiment and it surprised me haha.

@@veolouxx??
True. Rather watch this then go to school for hours
Moral of the story:
If the grenade is on the ground jump on the pool,
If the grenade is in the pool jump to the ground
and if there's a grenade in both the pool AND ground... i guess go to the ground.
@@tailzz6969 no. You should fly instead
@@Silrak50 tf was I thinking? of course!
Or you can just stay on the ground and kick the grenade into the pool
@@teslamodely01 then it would go off 😑
Is it odd that this is the first mark Rober vid I've ever watch
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).

Air compresses, water does not. A thunderstorm 20 miles away is almost silent. But an undersea earthquake can cause tsunami waves for 200 miles.
So, how close to a ground earthquake do you have to be to actually feel it? Does the ground absorb shock waves too?

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.
I love your video ❤ keep it up 😊
Mark: NASA Scientist
Also Mark: "silver ball thing"

Maybe hes trying to help us understand better since we don't really know much scientific words idk
loror9 you mean JPL, JPL and NASA is different
@@jm56585 Except JPL is owned by NASA and Mark himself says that he works at NASA. Just like how you still work at a restaurant, even if you're only in the kitchen. It's a part of the larger organization so you are still working for the restaurant or in this case, NASA
It’s 3:34

Simple solution:
Kick the grenade that is on land into the water
Ishaan Pahuja kicking it far away from u but if its not that far then ur ded
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.
Bastion Barrick given he said he was 15 feet away I think you’d have time
Copied, either that or you just thought that, bc that’s what I thought
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.
Now if my teacher would put this video up, I would of been raising my hand for every question she asks aster playing the video
Fantastic vid. Loved it!
*Enemy throws the grenade*
