* Vacuum cleaners in the early 20th century were large, powered by coal, and required three people to operate them. Other early vacuum cleaners had to be parked outside a building and had long hoses that went through the windows. Yet another early version of the vacuum was installed in the house cellar and connected to a network of pipes that led to each room in the house. * According to Irish legend, Jack O’Lanterns are named after a stingy man named Jack who, because he tricked the devil several times, was forbidden entrance into both heaven and hell. He was condemned to wander the Earth, waving his lantern to lead people away from their paths. * The first feature film created solely with Computer Generated Imagery (CGI) was Toy Story (1995). Over 800,000 hours of mathematical equations went into the film, which works out to more than a week of computer time for every second on the screen.
