On one side of this beaker mug is a caffeine molecule enameled in white. On the other side it has graduations up to 350mL (the total volume of the mug is 400mL). When coffee or any other dark-colored drink is added, the molecular structure becomes very visible. Made of heat-resistant borosilicate glass, this mug makes an excellent Christmas gift or birthday present for your favorite scientist!
