If two grenades fall near you, one on the ground and another in the water, what would you do? Would you dive in the water a certain distance away from the underwater grenade hoping that the water will shield you from the shrapnel, or would you dive to the ground hoping that not a lot of the shrapnel from the surface blast would hit you? Mark Rober teams up with Kevin (TheBackyardScientist) to figure this out. Their video is very good, so I will leave the explanation of the science up to them, but you can also check a written version here.
