World on Instagram: "It might look like a normal boat, but it hides something wild underneath. As it lowers into the waters, powerful machines suck the water out of a sealed chamber, creating a dry space where you can walk underwater. No wetsuits, no scuba tanks, just you and a clear view of the sea all around. It’s like stepping into a hidden room at the bottom of the waters.
