With the FIFA World Cup less than two weeks away, fans planning to attend matches at Levi's Stadium will have to navigate an extensive code of conduct. It's a reflection of the intense national pride the tournament ignites.

Guests are permitted to bring food into Yankee Stadium for individual consumption. Items such as apples and oranges must be sliced or sectioned. Empty, reusable, non-glass water bottles that do not exceed 24 oz in size, and clear factory-sealed plastic bottles of water, 1 liter in size or smaller, are also permitted.

Along with vuvuzelas, the rules ban whistles, air horns and other loud noise-making devices, while musical instruments larger than 12 centimetres in any dimension require prior written approval from organizers. Drones and reusable water bottles are also prohibited.
