The deepest swimming pool on Earth

The deepest swimming pool on Earth: "Located in Brussels, this swimming pool is perfect for learning how to dive or for fine-tuning your skills before you hit the deep ocean. It’s 105 feet (33 meters) deep with 2.5 million liters of chlorine-free warm water. But the pool isn’t just used for practice; it’s also a tourist attraction. Everyone is welcome to test dive with instructors who will provide training if you are a beginner."
