👉 The hostel fluid, also known as the hostel water or pool water, is a naturally occurring mineral-rich water found in many hostels and public pools worldwide. This water typically contains high levels of minerals such as calcium, magnesium, bicarbonate, and sulfates, which contribute to its distinctive clear, often milky appearance. The mineral content can vary depending on the local geology and water source, but it generally provides a refreshing and invigorating experience for swimmers. While the fluid is safe to drink in moderation, it's important to avoid ingesting large amounts as it can cause gastrointestinal discomfort. The mineral-rich environment of hostel pools also supports aquatic life, making them popular spots for swimming and relaxation.
