Weird stuff, expensive stuff, old stuff, new stuff—as long as it's tangible (and not a body part), Brooklyn Brainery wants you to show it off. Did you find a rare gem while roaming around in Bushwick? Do you have a family heirloom that you haven't broken yet? Bring it all! The hosts will curate, and if you're chosen, you get five minutes to share your cool collectable with the audience, plus you won't have to pay for your entry ticket. It's okay if you don't have anything to share, because this interactive audience is just as much a part of the experience as the presenters. And they need you to chose who wins.
