At that location, swimmers can swim between the two continents.

The crystal-clear waters are in Thingvellir National Park, in Iceland. Silfra.org says divers can see underwater for more than 100 meters. According to The Indian Express, the temperature remains between 35.6 and 39.2 degrees Fahrenheit.

What makes the video so remarkable is that the water is along the Mid-Atlantic Ridge, where the continental drift occurs.

The plates started moving over 150 million years ago.

Divers swim along drift, where the tectonic plates drift 2 centimeters each year, according to Silfra.org.

The video has been viewed over 24 million times since it was posted last week.
