Click Cube

The sugar cube was invented by Jakob Christoph Rad, a Swiss-German chemist. Rad was the director of a sugar refinery in Dacice, a town in what is now the Czech Republic. He invented the sugar cube in 1843 as a convenient way to package and use sugar.

Rad's wife had injured herself while trying to cut a lump of sugar, which led him to develop a safer and more convenient form of sugar. He patented his invention in 1843, and the first sugar cubes were produced in 1843 in Dacice. The invention quickly spread throughout Europe and became a popular way to consume sugar.
