A German motorist was surprised by euro notes swirling in the air around her car so she hit the brakes and collected a “substantial amount of money,” according to Reuters.

A police spokesman said the 24-year-old woman saw the money flying through the air in her rear view mirror late on Wednesday. She pulled over and tried to collect all the notes, unsuccessfully.

A spokesman at Worms city hall said police were withholding details on the exact sum and location of the find in the hope of learning more about the money’s origin.
