Measuring the response of a viscous liquid approaching the glass transition provides vital information about this important process, especially across a wide range of time scales. Hecksher et al. consider the mechanical response of silicone oil across an impressive 13 decades by combining seven experimental methods. This molecular glass former follows scaling laws derived in the 1980s called mode-coupling theory. The strategy is generally applicable to a variety of substrates and should provide deep insight into the enigmatic glass transition.
