Mono Monday: Secret

Brits of a certain age should need no explanation as to why this fits the "Mono Monday - Secret" challenge. Younger blippers and those from other countries may (or may not) find a satisfactory explanation here.

This shot is what happens when you get stuck inside on a hideously wet bank holiday Monday with a brain full of trivia. I have to say this is the first time I've felt the need to spend money on a prop for a blip and I now have the problem of what to do with 1.5 litres of fizzy sugar water which is way too big for my undersized fridge!

Thanks to Aphid for hosting the challenge and sparing you from yet another shot of the big puddle outside my window.
