According to the Telegraph (big pinch of salt needed then) bottles of water, mobile phones, picnics and umbrellas could be banned at the London 2012 Olympics.

(A list of rules says the following items are banned: “Food, alcoholic and non-alcoholic beverages, liquids in containers of greater than 100ml in size, umbrellas, horns, whistles, drums, rattles, musical instruments, or any other devices that in the opinion of Locog may disturb a session (including mobile telephones), flasks, Thermoses and in general any material that Locog may deem dangerous or that may cause damage or disruption to a session.” I think they should ask stupid bureaucrats to the list too.)
