aluminum foil

A common item found in almost every home is all it takes to turn a regular cooler into a super cooler where the ice seems to last forever.

Apparently, aluminium foil does more than keep food fresh in the fridge. You can also use it in the dishwasher for some amazing results.

Apparently, there are short term benefits but they come with long term risks. And there's a chance you might wind up looking kind of stupid too.
