The Maldives is known for its fantastic beaches, clean waters and huts on sticks which you can stay in if you ever go on holiday there. But at night sometimes something amazing happens to the beach - it glows blue.
Will Ho was out in the night on a beach in the Maldives and was astonished to find that it was glowing blue. The reason for the blue glow is because of millions of bioluminescent phytoplankton - they're tiny organisms that glow just like fireflies. But these little organisms glow a beautiful blue.
