Want to take small flask of liquor to jury duty?

If I sneak a small flask of liquor in with me to sip on when no one is looking, what would happen if I was caught with it? Would it simply be them asking me to dispose of it? Would I be arrested? If all they do is ask me to throw it away, I will risk it. I am over 21 so it is not an age issue. I just know they don't sell alcohol inside, so I want to sneak some in.
