If you type the words “let it snow” (without the quotation marks) into the search engine Google.com or Google.ca*, you probably won’t be surprised when Google gives you back a list of links to the classic Christmas song.
What might surprise you, however, is that it will also start snowing on your computer screen!
Eventually, so much “snow” will fall that your screen will fog up. But don’t worry, you can click on Google’s “defrost” button to clear it again. You can also use your mouse to “wipe” the screen clean.
