Schrödinger's Cat Mug Set

Pour a mug of your favourite hot drink, and watch as the rising temperature lets you observe the cat, collapsing the wave form and revealing whether it is alive or dead.  This pair of temperature-sensitive mugs each have a different image, and you won't know the fate of the cat until you pour!  Model the 'many worlds' hypothesis by using both mugs at once.

Set of 2 porcelain mugs.
Each mug measures 9.3cm high, capacity 300ml.
Not dishwasher safe.
