One woman has came up with an ingenius trick on how we can now check if our refrigerators are still in optimal working condition – with just a single mug of water and a penny! With such an experiment, you’d never have to worry about having spoilt vegetables or fruits in your fridge again.
An idea developed by Sheila Pulanco Russell, she demonstrates a fridge-mug experiment with simple tap water. It is an extremely easy experiment – if the penny freezes, its a good sign – your fridge’s able to keep your groceries well-chilled and frozen. If it isn’t, it probably tells you that you’d need to buy a new refrigerator to prevent food spoilage – try this at home now!
