Doctor Who Color-Changing TARDIS 2 oz. Glass Set of 4

Add a cold beverage to one of these clear 2-ounce mini-glasses based on the BBC's Doctor Who television series and the image of the TARDIS or series logo magically changes from light blue to dark blue! As the glass warms up again, the image changes back to light blue. Now, that is cool!
