A viral life hack suggests placing a 1-rupee coin on a frozen glass of water inside the freezer to check if stored food is safe after power outages. If the coin stays on top upon returning from a trip, the food remained frozen; if it sank, the ice melted, indicating the food may have spoiled due to power loss. This trick helps prevent food poisoning caused by consuming spoiled dairy or meat products. https://punjab.news18.com/news/ajab-gajab/why-people-putting-1-rupee-coin-in-freezer-know-smart-fridge-trick-before-travelling-for-few-days-sk-975401.html #Creator program
