Video explores world's deepest diving pool
A video explores the 40-metre-deep 'Y-40 The Deep Joy' pool in Italy, which the Guinness World Records recognises as the world's deepest swimming pool for diving. Opened at the Hotel Terme Millepini in Padua in June 2014, the pool has an area of 21x18 metres. It features underwater caves and a transparent, suspended underwater tunnel for visitors to walk through.
