Keeping everything in your refrigerator at the right temperature is essential for storing food items. It’s important to find the right temprature. If it isn’t cold enough, the items stored in your fridge will expire quickly or develop harmful bacteria that can make you sick, and nobody wants that.
On the other hand, when your fridge is too cold, it will freeze food items that you might not want to have frozen or that can’t withstand the freezing temperatures. As this person experienced, their bottle of tea cracked from the cold temperatures and spilled the tea all over the fridge. The tea then preceded to freeze on the shelf of the fridge. Weirdly enough, the water right next to the tea seems to be just fine.
