Drag the tab, slowly
Take the pull and move it down. The teeth part in pairs just ahead of it and the page splits into a V behind. Go slowly and you can watch individual teeth release, which is the bit worth having and the bit most copies leave out.
Stop anywhere and it stays there, half open, still joined below the head.
One day on the homepage
It was a doodle for the birthday of the engineer who worked out the modern zip fastener, and it ran for exactly one day in 2012. Pull the zip, page opens, results underneath about the man himself.
Doodles come down. That is why google zipper online, google zipper play, google zipper game and google zipper doodle all lead to rebuilds now rather than the thing itself.
Nobody spells it right
Google ziper, google zippe, google sipper, zip google, zipper google, googlezipper, google zíper. Search sorts them all out. The strangest one is google zipper 2048, which is two unrelated browser toys glued together by autocomplete and nothing else.
For a doodle that never came down, the maze at google pac-man is the one to try. For another thing you drag rather than click, there is grogu google.
