Braille was invented in 1821, though probably not in one day. Louis Braille was twelve years old when he invented the system, though it was not widely accepted at the time. The Braille system became the official reading and writing method of the National Institute for Blind Youth only six months after Louis Braille's death in 1852.
The water Displacement method is simply when there are 2 cups and a tray. The first bucket has a spout, and is filled to the max with water. Then a second smaller bucket is placed inside. The tray on the bottom collects water that has spilled out (the water that spills is equal to the objets mass). When objects are placed in the small bucket, it pushes water out of the the larger one, and fills the tray. The tray can then be weighed to see how much mass the object has. Hope this helps! =) -A twelve year old
