BOOOOOOOOM.
Here's what the shock wave coming off an explosion would look like if you could freeze it in time.
The explosion was carried out at Canada's Experimental Proving Ground in Alberta, a site that's been used as a research and training facility since 1941.
A shock wave is an wave of high pressure that spreads out from an explosion (and anything that travels faster that the speed of sound, too). Usually you just hear a shock wave rather than see it: they create the boom you hear when a firework explodes and the rumble of thunder.

The still comes from a video by the Canadian Armed Forces that shows how they "train for defence against deadly threat agents and explosives."
It's all a bit dramatic and there's a lot of weaponry and patriotism, if you like that sort of thing.
