An enormous World War II relic, known as a ‘Tallboy’, was detonated safely underwater by navy demolition specialists in Poland.
This is the biggest explosive used by the British Royal Air Force in 1945. It weighed a whopping 5,400kg, including 2,400kg of explosive.
The ‘Tallboy’ was first discovered last year in Spetember at the bottom of a shipping canal in Poland.
750 people were evacuated from the area near Piast Canal, outside the town of Swinoujscie. Navy demolition specialists used remote deflagration, which involves burning out explosives, but in the end it was detonated without damage.
Experts are not sure why the bomb did not go off back in 1945.
