- cyberferret 8y agoAlso note the ground around the point of explosion being turned over by the shock wave as it moves out. That video was a great illustration of how the pressure wave moves out in all directions as an expanding ball - it is too easy to misinterpret the wave as a flat circle moving outwards from a point, rather than a sphere.
