Phoenixville, Pennsylvania is the home of the theater where the blob once oozed through the projection booth windows and caused the audience to flee en masse. In 2000, the theater started Blobfest, which celebrates its association with the movie with a reenactment of the run-out (which one must purchase tickets for long in advance to participate), a scream contest, multiple screenings of The Blob, and an actual appearance by the blob itself! Turns out it's small enough to live in a bucket (the scenes of its attacks were achieved with miniatures) and is in the possession of a movie memorabilia collector. In addition, there is a plaque in the balcony with a brass replica of the blob on it that one is encouraged to rub for luck. Check out this article from The Onion's A.V. Club for more about this ultra-cool event!
