Big Brother has told housemates that they'll be lied to twice this week, which has put a lot of doubt in to their minds, not helped by the fact that they were told nominations were voluntary this week but had to be done between 6 and 9am.

So this afternoon they've been given a map telling them to look for long lost hidden treasure, and have been given a mirror on a pole, a torch, two spades and various other treasure seeking equipment.

Things started off pretty slowly and without a lot of organisation - much as you'd expect from a bunch of Big Brother housemates - but thinks took a turn for the better when Big Brother started to say that housemates were "cold" "hot" "hot but not boiling" and finally "boiling" at which point they'd started to dig up patches of the grass in a manic attempt to try and find something... anything...

And the first thing they did find was a washer, but that was soon disgarded as not being the treasure after Eugene found a paving slab exactly where they were digging.

They've also found bits of wood which appear to have been placed there to make it obvious that there is something worth digging for (instead of just builders rubble) and Science has been soaking the ground to make it easier for Anthony to dig deeper. Not to mention wider. The garden looks a bit of a mess, and they're well over the 20 minute time limit that Big Brother had set them.

Found it....!
At just after 8pm they'd finally dug deep enough to be able to lift a slab which was hiding a black and gold treasure chest, which seems to contain chocolate coins, although there's still confusion over if that's the whole task and if they're going to be rewarded with more for having found the treasure - with housemates saying that they "want some wine" - seeing as they're never happy with what they've been given.

A few minutes later the store room had been opened to allow housmates to access their reward - ice lollies and a jug full of chopped fruit in juice.

More updates from Day 46 as they happen...
