 The show first received international attention in 2006 for having people walk across a swimming pool filled with a non-Newtonian fluid, a suspension of cornstarch and water called oobleck, that was mixed in a cement truck.This experiment was performed in an October 2006 episode of the show and was repeated with a new batch of oobleck on the Christmas Eve special episode due to its popularity.In 2007, Cuatro signed an agreement with YouTube that allows clips from Cuatro programs, including "El Hormiguero", to be showcased on the site.
