Watch: How to make the smallest cup of coffee in the world

Weaning yourself off coffee? You might want to try this! When designer Lucas Zanotto was asked by Finnish coffee company Paulig to create an ad for them, this is what he came up with. To brew the smallest cup of joe in the world, he uses one bean of Kenya AA-plus Karindum coffee, "grinds" it with a nail file, drops the fine grounds into the tiniest coffee filter you'll ever see, boils the water over a candle, and pours the dark brew into what looks like a vial.
