In the Northern Hemisphere, it's wintertime, the coldest time of year.

Regardless of where you live, this savvy grandmother came up with a hack to keep your residence as warm as possible during the winter months. Can you guess what it is?

One of her most popular videos is titled "Insulate A Window With Bubble Wrap." The video has amassed a whopping 3.3 million views since it was posted on Jan. 5, 2014. The 76-second video is short, sweet, and to-the-point. Better yet, it contains absolutely zero product endorsements or sponsorships, providing viewers with a helpful, unbiased trick to keep your house warm during the winter months without having a special interest's product, service, or brand shoved down your throat.

All you need is a sprayer bottle filled with water, bubble wrap, and scissors. Cut pieces of bubble wrap to snugly fit the glass surface of your windows. Next, spray water on the interior surface of the glass.

Simply place the bubble wrap snugly against the glass and pat it down lightly. It'll stay in place until you're ready to remove it!

This hack does not permanently harm your windows.
