Pic of the week: Francine the bubble queen

These pictures were taken at the first ever King Of The Bubble contest, which requires contestants to produce the largest, clearest, longest-lasting and most perfectly rounded rings. It's a specially-built pool in Brussels, Belgium, 100ft deep (the deepest in the world).

The eventual winner, beating nine finalists, was 31-year-old Francine Kreiss, from Hyeres in France (above).
