Well.. I didn't see that coming!

Started having these liquid "shake" lunches, and just come to the kitchen to clean it..

I'd forgotten what a colleague had told me NOT to do when cleaning them, and well.. did it anyway..

Filled it half full of BOILING water,

put the springy agitator back in,

screwed the lid on,

pressed down the drinking cap

..and shook it like a bartender making a cocktail...

"Ooh, that's warm" I thought as I  popped the lid..

BOOM!!!
