And on the dashboard, oh look at this, a covered blue bubble.

The thing is a blue bubble called Futura and, wonder of wonders, it can park itself.

As I pulled out, a patrol car rolled up, blue bubbles flashing.

A Chevrolet with a blue bubble on the dashboard roared by.

He wondered if the air was good in this blue bubble.

A hornet came through the curving wall of the blue bubble, hovered over them, and set down silently.

Wingert heard a click, and abruptly a shimmering blue bubble of force sprang up around them.

The blue bubble was close; now it curved below us.

It is sometimes called the blue bubble, or man-of-war.
