The world's smallest magazine cover is 2,000 times smaller than a grain of salt

No, National Geographic Kids didn't forget to buy colored ink -- that's a blown-up view of the smallest-ever magazine cover, created by IBM to set a Guinness world record. The tech firm used a miniscule, heated silicon "chisel" to etch a polymer image measuring just 11 micrometers by 14 micrometers, or 2,000 times tinier than a grain of salt. The image is more detailed than you might expect at such a miniscule size, too.
