The sacred birthplace of Viagra will be transformed into a massive carnival party palace this weekend by Winkel & Balktick, a pair of event producers who've been putting on shows at the nightclub where Sleep No Moreis staged. (They've also staged a "warehouse wilderness campout" that lasted all night in a raw space equipped with panoramic surround sound.) On Saturday night they'll take over the 50,000 square foot Pfizer headquarters in South Williamsburg for an event called "Laboratory."

The eight story complex of laboratories closed in 2008, but it's recently found new life as a home to small-batch artisanal food businesses like McClure’s Pickles, Brooklyn Soda Works, and Kombucha Brooklyn. Now we can add site-specific art parties to the list. Winkel and Balktick are putting together a science-themed rager on the first and third floors of the complex. Expect stilt walkers in custom-length lab coats, four live bands, DJs, aerialists, circus performers, Bunsen burner cocktails and plenty of ironic arguments about helium's place on the periodic table. Oh, and drugs. Mustn't forget to bring the drugs!

“We’re not doing an art-party where you can go and sit in a chair and watch a performance — it’s an experience,” Mark Winkel tells the Brooklyn Paper. “You can be there for seven, eight hours, and not get bored." Tickets, which currently cost $30, are still on sale.
