The room looked as if a bomb had gone off.

I wouldn't have known the bomb was going to go off.

I had just gone down the road when the bomb went off.

Then just as he was getting to his feet, a third bomb went off.

And then the whole bomb went off in my face.

People were having a good time, until the bomb went off.

A mother and her children who just happened to be going by when the bomb went off?

They think he opened a door and the bomb went off.

When the bomb went off, he called the fire department.

When the huge bomb went off, little could stand up to it.
