Did you know sandpaper has been around for a long time? ๐
The first kinds of sandpaper were made in China during the 13th century! They used materials like crushed shells, sand, and even powdered gemstones! ๐
Later, in the 1800s, people in the
United States created sandpaper with glue on paper, which we still use today. In 1921, a man named John A. Ransom invented the first sandpaper machine, making it easier and faster to make sandpaper! ๐
