Pour hot water into these two identical heat-transforming mugs to reenact Erwin Schrödinger's famous thought experiment. Steamy water goes in - the heat changes the mugs - and now you find out which mug has the live cat! Schrödinger' cats have been fine - and not - and both - since 1935 and we're still... concerned. 

Each mug holds 10 oz/300mL.

Care instructions: Gently wash with warm water and soap. Do not machine wash.
