Dr Who disappearing TARDIS mug
I was given this mug on the weekend as a late Birthday present and it may well be the only time I’ve seen heat-reactive paint used to good effect.
Add coffee and the TARDIS disappears from the street, only to appear on the other side floating in space. Just love it.
It comes from The Unemployed Philosophers Guild which is stocked with interesting stuff. They also have the highly entertaining instructional video on the use of mugs – which includes the wonderful line “Mugs obey the rules of gravity.”
