Readers love their elemental cupcakes, especially the ones with sprinkles. The winner in this category is Sally B. Mitchell (@SallyBChemistry), a chemistry and physics teacher at Rye High School, in New York, for her Twitter photo of a deliciously crafted periodic table cupcake holder. A must-have for all chemists.

You chemistry lovers keep periodic tables all over the house. They’re featured on mugs, cutting boards, shower curtains, and more. The winner of this category is Tianfei Liu (@TianfeiLiu), who used the online form to submit this image of a beautiful handmade cup decorated with a periodic table in Chinese.

A number of the tables submitted didn’t fit into any of our main categories. But we loved them nonetheless. Our two favorites among these nonconformers (we couldn’t pick just one) are from professors José Barros (@zerozero43) and Ricardo Michel of the Federal University of Rio de Janeiro, who submitted these gelatin molds via Instagram, and from Jan Radford (@JanRadford), associate professor of general practice at the University of Tasmania, who submitted this amazing tile work via Twitter.

Who knew the periodic table was so fashionable? Of all the T-shirts, vests, shoes, and scarves submitted, the top choice in our book is this photo, submitted through our online form by Missy Westgate of Ottawa, Ontario. She writes: “When I saw the fabric, I knew it was perfect for my Dr of Chemistry husband!!”

Cuteness overload! Chemists love their periodic tables and their babies, furry and otherwise. The winner in this category is Lauren Langman, a chemistry teacher at Montour High School, in Pennsylvania, for submitting a Twitter photo of this future chemist.

Dmitri Mendeleev’s periodic table is 150 years old, and it has been depicted in myriad ways. Our favorite historical version is this one, captured on Twitter by João Victor Silva Néto (@thesn98), an undergraduate student at the Federal University of Rio de Janeiro.

The periodic table is beautiful to chemists, so they love to use it to decorate the places in which they spend a lot of time: their classrooms and desks. Our favorite in this category was submitted via our online form by David Harvey of North Little Rock, Arkansas. Harvey labels the photo as follows: “My son putting samples in a periodic table display he built for his high school.”

Chemists like to take their periodic tables everywhere, whether on credit cards or key chains. The winner of this category is Robert LeSuer (@bobthechemist), a chemistry professor at the College at Brockport, for his 3-D printed version, shared on Twitter, depicting the first ionization energies of the elements.
