Cash bomb...
 

I have been thinking of how on earth they can make this fair, and can only think of this...

8 'timebombs' in the garden. All housemates are told that there is 50/75k inside one of the bombs and if they chose it, they will get the money but be immediately ejected. They have to chose if they want to pick a bomb or not, and argue between themselves for which one if theres a clash..

This, IMO, would be the most interesting way to do it, as it will give them ALL a chance, and will also show up which ones are genuinely there for the experience (that said, I think they would be idiots for not taking the cash at this point)

Only problem with this is IF Marc is there, and happens to pick the one with the cash, there will be endless fix accusations. But there will be that anyway so who really cares..

I don't think they should do it at all. They are again shooting themselves in the foot
