Richard Hammond shows how a shockwave can be seen

Explosion in slow-motion

Cannot play media. Sorry, this media is not available in your territory.

The power of an explosion is not from the blast itself but from the shockwave it creates - despite it being invisible to the naked eye.

Richard Hammond has used the latest camera technology to capture an explosion in super slow-motion to see the destructive power of the shockwave in action.

Thousands of pounds worth of gunpowder were used to create the controlled blast in New Mexico.

Richard Hammond's Invisible Worlds can be seen at 2100 GMT, BBC One and BBC HD, Tuesday 16 March and afterwards on iPlayer.
