While the clip doesn’t reveal how Barry survives, it seems to point toward Ralph lending a hand.
Now, if she only used her powers to steal jewels, she might not pose that huge of a threat to the innocent of Central City.

Sure, her ability to float people will allow Ralph to make a Willy Wonka & the Chocolate Factory joke, but it will also nearly send Barry plummeting to his death.
