When I first looked at Wikipedia, I found clicking on links and seeing where they took me could be enlightening. So I thought I'd make a game of it and I have therefore just invented Ten Steps Of Wikipedia. You start and finish with chosen words or names or things and have to follow links on the wikipedia entry to the next entry.
On my shelf is a DVD of Harry Potter, so that can be number 10.
The starting point is a random word generated on this site - and the obscure noun produced is (1) Panguingue - which is a gambling card game similar to rummy particularly popular in (2) Las Vegas - the most populous city in Nevada and an internationally renowned major resort city for the gaming, shopping and entertainment and was named by (3) Antonio Armijo who found it after following a tributary up the (4) Colorado River - which features a dam finished in 1936 called the (5) Hoover Dam. The first concrete was placed in the dam on (6) June 6, 1933 - the 157th day of the year , and the day in 1906 that (7) Paris Métro Line 5 was opened. One of the metro stations on the line is (8) Gare du Nord. This is the terminus where you can catch a high speed Eurostar train to (9) St Pancras International station which is used for the exterior shots of King's Cross station (which is actually next door) in the (10) Harry Potter films.
And that's how you go from Panguingue to Harry Potter in 10 steps!
