My fave game is to get about 8 nappies, and 8 different choc bars. Microwave each choc bar until soft and then mush it up and put one in each nappy. Give everyone a piece of paper numbered 1-8 (and number the nappies) and they have to guess which choc bar is in which nappy. They can smell and look at it. It is disgusting but hilarious!! xo
