Underwater jigsaw competition!

An underwater jigsaw puzzle contest was held last month in Taiwan. Yes, you did read that correctly. The participants of the competition completed puzzles underwater wearing scuba gear. The organiser  decided to hold the event underwater in the hope of drawing attention to the importance of conserving the marine ecosystem.
While many of the participants were capable swimmers and scuba-divers, getting the hang of breathing slowly and trying to counteract buoyancy as they pieced together the magnetic puzzle pieces took more effort than some had expected, providing quite a spectacle for the spectators.
