What’s white, then brown, but can’t be found?

This common household item starts its journey pristine and clean, typically white, ready for its intended purpose. After use, its color naturally changes, reflecting the task it has performed. Then, with a simple flush, it disappears from sight, breaking down in water and traveling through plumbing systems, thus becoming "unfound" in our immediate environment.

Before the advent of this modern convenience, people throughout history employed a variety of methods for personal hygiene, ranging from leaves, grass, and even stones, to sponges on sticks used by wealthy Romans. The earliest recorded use of paper specifically for hygiene dates back to 6th century China, with mass production for the imperial court occurring by the 14th century. However, it wasn't until 1857 that Joseph Gayetty introduced the first commercially packaged toilet paper in the United States, sold as flat sheets.

The familiar perforated rolls we use today were popularized later in the 19th century by innovators like Seth Wheeler and the Scott Paper Company. Early versions were far from the soft product we know, with a notable selling point in the 1930s being that the paper was "splinter free." This essential item, often taken for granted, has a surprisingly rich history and continues to be a staple in many parts of the world, though billions still rely on other methods due to cost or plumbing limitations.
