    It's DEFCON 30 and the world is a tumultuous place. Maybe Putan has invaded NATO. Maybe China has invaded Taiwan or doubled down on its bid to claim the oddly sack-shaped "nine dash line". I think Pooh Bear may be trying to compensate for something. Whatever the current events, I'm going to claim WWIII is right around the corner and you should be prepared! Prepared to chill your beverage that is. If the world is ending, do you really want to see it out with a warm beverage!? I thought not! If I'm going out in a nuclear hellfire I want it to be with ice cold suds. So come on down and let's get prepped!

    In person only
    Friday 1100 - 1400
    Maybe something on Saturday if beverage remains and interest exists.

    Hey yall! Its BCCC time again.
    • Same categories (hacked and unlimited) as last time. Bring a contraption for the unlimited class or build it at the event for hacked.
    • The supply store with dry ice, regular ice, duct tape, and maybe rubbing alcohol if I can find it will be available.

    Rules,

    Beverage will come to you in a red solo cup. You must bring the beverage back to me in that cup for judging.

    Target temp is 34F or 1C.

    General rules remain the same,
    • Thou shalt have a DEFCON "badge".
    • Thou shalt not have more then 3 people on a team at the table during qualification runs. Larger teams are allowed for setup but only 3 operators during qualifying runs.
    • Thou shalt dispose of thine own test fluids.
    • Thou shalt not used a commercial pre-built unit. You must build your own contraption
    • Thou shalt not adulterate the beverage! No pouring it over ice, no mixing in cold fluids, no pouring over dry ice, no adding liquid nitrogen etc etc..
    • Thou shalt not excessively endanger the event. If your contraption is flammable, contains compressed gasses, is otherwise hazardous you will need to explain to me how you have mitigated the risks and I will make a final determination. So please, if flammable, have an extinguisher, if it contains pressurized gasses over a few psi, please have completed a hydro static test of at least 2x times the max expected operating pressure and have a safety relief valve at no more then 1.5x! Note CO2 can go solid in valves when vented so keep that in mind. This is an indoor event, venting hydrogen fluoride is a no go. That said, we have never had to disqualify someone and that will remain a fact so lone as everyone uses common sense! Lets do this!
    • Thou shalt have fun! Seriously, don't fuck this one up. Last thing we need is some damn talking ponies showing up and bringing all the bronies to the yard. I lived in Baltimore during the dark years, I don't need that.
    Finally, as with every year if you provide me a sub 4 kelvin beer that you chilled at the event you automatically get first place, my eternal love and admiration, and IDK a drone or something. I'll have to figure out the prize for this one on the fly because nobody is actually going to do this. TO NOTE the method must be repeatable, no venting large amounts of helium!

      I look forward to my first one of these. An old webpage mentions getting registered for this contest. Is there somewhere we need to register, or do we just show up?

        (former BCCC helper here) we've always accepted walkups. If you plan to build and bring a machine then you should probably get in touch with the Chairman but otherwise we'll be ready for folks who show up with no supplies but lots of great ideas!

      When you reply, using an "@" reference to the organizer may help get their attention. I will try it here for you:

        The BCCC team is building up our stockpile of random goodies to help you on the path to victory! Or at least on the path to thinking about cold brews and how the come to be. We'll have some of these items (not inclusive nor is it for sure)
        salt
        ispropyl
        tubing
        tape
        buckets (limited)
        foil
        etoh
        compressed air (limited)
        funnels.

        You can always find lots of interesting things in your hotel room and around the con...don't steal anything but repurpose if it's the right thing to do.

          Also, contests will be at the Caesars Forum...this is NOT at the Caesars Forum Shops! It's new and it's behind (east) of Harrah's and north of the Eye (the big wheel). Here's a map....https://defcon.org/images/defcon-30/maps/forum.webp
