I'm thinking about an idea that could make money and get people messy at the same time... what I propose is this:

The event takes place in Leicester Square on a Saturday night/Sunday morning, and we offer people a gamble... survive a patience test for a set amount of time to win 40-80. If the contestant gambles 10, they have to remain seated for 10 minutes to win 40; 15 seated for 15 minutes to win 60 or 20 seated for 20 minutes to win 80.

During the time, onlookers are invited to pay 1, 1.50 or 2 for a cup of something messy, and they have a minute to try and get the contestant to move. If the contestant moves from their seat they lose their money and it is given to the person who made them move; if the contestant remains seated throughout they win 4 times the amount they gambled...

Anyone want to help turn this into reality?
