Historic heat waves have rocked parts of the United States this week, leading to record-breaking temperatures over 110 degrees Fahrenheit in cities like Portland, Oregon.
People took to social media to share ways people in homes with no air conditioning or poor air conditioning could fight the heat and stay cool. One method in particular stood out because users claimed it was both cheap and effective: covering windows with aluminum foil to reflect sunlight and the heat back outside.
Since I don't buy aluminum foil often, I00'm not sure how cheap it is - though probably less expensive than an a/C unit.
