A few centimeters to cultivate two microorganisms that grow for 24 hours at about 100 degrees Fahrenheit was what the American Society for Microbiology needed to celebrate Christmas this year. The unusual "card,"  complete with a tree, all the balls and a star on top, could be a worthy contender in #chemistree, the Twitter hashtag that collects the best, scientific-themed Christmas trees.

The most classic, the chemical Christmas tree, could be the origin of this movement on the Internet if you stick to the name.

However, these are more original — plastic gloves and even quantum dots on water-repelling paper.

Our #Chemistree is a pleasure of superhydrophobic paper and red/green quantum dots… #realtimechem pic.twitter.com/bwP12pnCjS
