How can I set up an option to 'buzz-in' for playing games at a high school club?

[_Audio_Scars_]

So I'm making this game-show activity for my anime club at school. I have the entire game set up and ready to go. There is just one problem: I don't know how I should have the teams buzz-in to answer the question.

There are only going to be two teams, if that helps. I was considering raising a large colored sheet of paper to buzz-in but I don't know how I'd determine who raised their card first if they raised it within milliseconds of each other.

Any ideas at all are greatly appreciated! Thanks in advance!

Hi, I just created an anime & gaming club. We're really new so we're looking for members and don't have a definite place like a building other than my apartment so for now its just going to be really small unless we attract more members into the group. It's just a friend and I currently and I'm not very talkative so we could really use an outgoing talkative person to help us out haha! I've made the website, facebook page and facebook app so far. When we gain more members we'll most likely meet-up at my place. We both attend Phoenix College so we're trying to get a club going there as our main headquarters so to say.

Anyway check out the website at: http://phxanimeclub.webs.com/

Everything is still in development and ideas are flowing haha but without members we can only go so far or it would just be for the two of us you know? Hope you become interested and we end up as Otaku friends xD

wish I was in an anime club in high school.
