Simple game - experiment with audience. You tell to the audience that you have 20$ and everybody can try to buy this cheaper. But there us the catch - second bettor pays the double amount of the first bettor. It means that if anybody trying to buy 20$ for 10.5$, it means that second place bettor will pay 21$. It leads to the situation when people sometimes pays even more than 20$.
