Approximately 600 residents living near the Frankfurt's River Main in Germany were asked to evacuate due to a bomb threat dating back almost 80 years.
Divers doing a routing maintenance dive near the Alte Brücke (Old Bridge) on Tuesday discovered a bomb that had been submerged since World War II, according to German news agency Deutsche Presse-Agentur GmbH (DPA).
The antique bomb was detonated on Saturday, 08:00 am local time, creating a massive explosion from the river's water.
And it went off without a hitch.
Divers returned underwater to make sure the device was safe.
The explosion is a sight to behold.
Even from afar, the wall of water shooting upward looked like something from a movie.
The BBC reported that the discovery of wartime bombs and other war munitions are not uncommon.
Such routine inspections taking place is reassuring, considering the amount of water traffic taking place every day.
Some expressed concern over the well-being of marine life.
Visibility underwater was "zero" and left a crater measuring 5 meters wide after the detonation, according to a local publication.
Despite the magnificence of the metropolitan geyser, the real threat of such a detonation in the city was still terrifying.
Last year, Berlin police led another controlled detonation of a wartime bomb that was discovered during a construction work in Heidestrasse.
The BBC reported that several unexploded bombs from World War II are found every year.
Routine searches are ongoing since it is believed there are 3,000 unexploded bombs still buried throughout the city.
