Explains the strange pattern of Transits of Venus on a paper plate. Two transit will occur within eight years (e.g., 2004 and 2012), then there will be a gap of 105.5 or 121.5 years until the next 8-year pair. Producer Nick Ducoffe narrates this two minute demonstration adapted from http://transitofvenus.nl/wp/2012/02/1... (details).
