Derby #56: Your Favorite Element
Where would we be without the elements, those 117 different atoms that form the building blocks of all matter? Nowhere, that's where. So pick one of your faves and celebrate it in a t-shirt design. You can depict the atom, show us something made from it, riff on the name, whatever - as long as the focal point of your design is one element and only one element. (So, for instance, "water" or "nitrous oxide" would be off-limits as themes because two elements get more or less equal billing.)
Make the element the first word in the title of your entry, followed by a colon and the rest of your title (e.g., "Helium: the Silent Killer").
