In article number 1603351, J. P. Ge and co‐workers demonstrate a portable and disposable photonic crystal based “test paper” for convenient monitoring of viscosity for many liquids with the requirement of little samples. The viscometer measures the viscosity according to the infiltration time of viscous liquid, which can be acquired by spectrometer measurement or naked‐eye observation due to the change of structural colors.
