For some couples, a cookie-cutter greeting card from Hallmark just won’t do. Pun-loving Canadian chemist Nick Uhlig has the answer for nerdy scientific couples looking to show off just how good their chemistry is. 

From “You Excite Me!” to “Nice Bunsen,” Uhlig’s Valentine’s Day cards are the quickest day to a chemist’s heart—or at least to a loving eye roll. He has seven designs, each with a scientific love pun and a heart-filled illustration. 

Each standard greeting card is $2.60 plus shipping. Buy them over at Redbubble

No one wants to just get a card, so be sure to check out our Valentine’s Day gift guide too.
