"Post on your blog an invention which was created due to a necessity. "






While Thomas Crapper is commonly given credit for inventing the first flushing toilet in the late 1800s, the first version can actually be traced back to 1596.  At this time, a British nobleman, Sir John Harrington, first engineered and invented a valve that could release water from the water closet (WC) when pulled.  Sir Harrington, who was also the godson of Queen Elizabeth I, recommended pulling the valve (“flushing” the toilet) once a day for sanitary purposes.
