It's not often you get to see what happens when a World War Two bomb gets blown up.
Police say they think it was a bomb dropped on Birmingham during the Second World War but that didn't explode at the time.
It was found on a building site.
Don't worry though - it was a controlled explosion carried out by the police, to make it safe.
People living nearby were evacuated to make sure that no-one would be hurt.
