Best noise making ideas!

I’m going to the Divisional game and trying to think of the best things I can bring to the game to do my part to have the Dome rocking!! What are some good things I could do/bring?? Besides my lungs ?

Bring a lot of pocket change. Buy a water. Drink the water and then put your pocket change in the bottle. Stuff the bottle opening with a napkin and shake it until your arm falls off. I did it last year and the fans around me thought it was ingenious. Only problem was, they couldn’t use it next game because we only had 1 home playoff game. This year; it could be on with the plastic bottle rattlers.
