When my former boyfriend and his family paid me a visit a few weeks ago, they brought a few small gifts, including this fun, temperature-sensitive mug advertising the 750th anniversary of the Pied Piper of Hamelin (otherwise known as Hameln, Germany).
Above is how the mug looks at room temperature. It’s dark grey, with a tiny logo and a line of text.
Add a hot beverage, however, and the mug’s glaze immediately begins to change colour…
…revealing the head of a rat. Awesome. :)
I’m particularly fond of the graphic on the mug because it reminds me of The Bloggess’ screaming stuffed weasel, Juanita. Also awesome.
