When a disgruntled group of Belgian firefighters wanted to press for speedier promotions, an ordinary street demonstration just wouldn't cut it.
Instead, the 150-strong group turned to their trusty water trucks to make themselves seen - blocking the streets of the capital Brussels with a spectacular foam display.
Making use of the hoses usually reserved for fires, the emergency workers sprayed foam from 20 trucks over a main road in central Brussels, blocking traffic in the busy area.
