The holiday season gets bigger and more hectic every year -- and maybe you're looking for a smaller, more adorable way to celebrate. Here's one: the world's smallest snowman. This microscopic frosty was built by the nanofabrication lab at London's Western University. He's adorable, but you'll need an electron microscope to see him in person: according to the lab's Tumblr page, the snowman stands at just three microns tall, or about 0.003mm. For comparison, a human hair is about 75 microns thick (0.075mm).
