platypus asked about the disappearing TARDIS mug I got as a PBS pledge gift many years ago, and given how rotten the weather is outside today, the mug seemed as good a subject as any for APAD(ish).
The middle photo is a bit of a cheat only because the TARDIS disappeared so quickly once I poured in the hot water I never had a chance to get the transition shot. I took it when I'd drunk half my tea.
