Humans may not be able to walk on water, but an invention by Li Weiguo let us bike on water! Behold the amphibious bicycle, made by water containers jerry-rigged into pontoons:
Li Weiguo's daughter Li Jin rides the human-powered amphibious bicycle on the water in Wuhan of Hubei Province, China on May 30, 2009. The amphibious bicycle made by Li Weiguo is equipped with eight water buckets as pontoons and adjustable vane wheels as driving power. This kind of bike can walk on land and on water.

But that seems to be an "invention" of the submitter - no where in the actual article do they claim to have invented a bike that works on both land and water (which of course has been done many many many times before).
This woman is a genius! Nobody has every successfully made a bike walk before!
