The man has achieved this feat in a single breath, sitting inside a transparent container filled with water.

The Guinness World Records shared a video of Sekar’s attempt on its Facebook page. “Using yoga meditation breathing techniques, Illayaram Sekar from Chennai, India has achieved a new record for the most Rubik's Cubes solved underwater,” they wrote in the caption.
