Bitch Better Have My Triethylene Tetramine Dihydrochloride.

Grad school can be tough enough without you having to pull rank. But when you absolutely have to do so—like, say your semester’s final joint term paper is due, and you need to let your chemistry lab partner know whose really running thangs—pimp slap them while wearing one of these Periodic Rings from It’s No Name.

Done up with each ring’s metal’s corresponding insignia from the famed table of elements, they’re available in silver ($280), gold, above ($2,350), and, for future Nobel prize winners only, platinum ($6,600). Aaahhhh, yeah: Sumn’s ’bout to go down, and it’s exothermic.
