😳 *WHY?* ❓❓
*Why does ice float on water?*
When water freezes, its molecules arrange themselves in a hexagonal crystal lattice held by hydrogen bonds. That open structure has more empty space than liquid water, so ice is about 9% less dense than water at 0°C and therefore floats. This is unusual: most solids sink in their own liquid. A floating layer of ice acts like a lid on lakes and rivers, insulating the water below so that fish and other aquatic life can survive the winter. If ice sank, water bodies would freeze from the bottom up and many freshwater ecosystems would not last through the cold season.

After Diwali: lighten the stomach, protect the lungs
🍲 Shift to simple, freshly cooked meals; cut leftover sweets and deep-fried snacks that strain digestion after several festive days.
💧 Drink plenty of water and buttermilk or lemon water to ease acidity and help the body recover from rich food.
😷 With AQI forecast to turn ‘Severe’ in Delhi-NCR, wear a well-fitting N95 mask outdoors and keep children, the elderly and asthma patients indoors as much as possible.
🏃 Move walks and workouts indoors until the smog eases; avoid early-morning outdoor exercise when smoke hangs low.
🩺 See a doctor promptly for lasting heartburn, breathlessness, chest tightness or burning eyes — do not dismiss them as “just the festival”.
