The largest box of popcorn was achieved by Cineplexx (International) with a volume of 52.59m³ (1857 ft³), which was filled in 1 hour and 57 minutes at an event outside Avenue Mall in Osijek, Croatia, on 16 April 2011. The event was organised by Cineplexx (International) to celebrate the opening of two new Malls, complete with two new Cineplexx cinema's in Croatia. During the first 30 minutes of the attempt, the box was filled with popcorn by foster children that had been invited to take part and then after a team of Cineplexx employees worked tirelessly to fill the remainder of the box. The popcorn was popped and bagged inside the Cinema and bought out to be used. There was also an independent surveyor on hand throughout the attempt and he was able to show me how he calculated the measurements of the total volume.
