As the weather heats up our homes are becoming increasingly unbearable. Fans are expensive to run, and leaving the windows open for long periods of time invites a swarm of flies and insects.
So how can you keep your living space cool without running up your electricity bill, or a hatch of flies everywhere? One little-known trick only a 68p roll of tin foil or kitchen foil - such as that sold in Asda, Tesco, Morrisons, Sainsbury's and Aldi, North Wales Live reports.
People desperately trying to keep cool have urged others to roll out kitchen foil and spread it in your windows, especially any windows that gets direct sunlight. Normally, when direct sunlight shines through a window, it magnifies the heat of the sun and makes your house even warmer - this is how greenhouses work to keep plants warm inside.
