Household Objects That Are Much Older Than Most People Think

As crazy as it may seem, contact lenses aren't actually a new invention. Stumbling upon the concept all the way back in 1508, Leonardo da Vinci published a paper called "Codex of the eye, Manual D", outlining the concept of "wearing a water-filled glass hemisphere over the eye".

Following his publication, many doctors made attempts at crafting the first pair, but the actual credit goes to German ophthalmologist Adolf Gaston Eugen Fick in 1888.

A staple of every home, the flush toilet continually saves us from a great deal of mess. But, when thinking back to how long they've been around, your first guess would be something like a few hundred years, right? (At least, mine was).

In actuality, some of the earliest flush toilets were made out of clay sewer pipes belonging to the Mesopotamians in 4000 B.C.

One would assume that any kind of "electronic" would have to have been created within the last century, but once again past inventors prove us wrong! Making its appearance way back in 1878, the first audio jack was installed into the first-ever telephone switchboard in Boston.

The Oreo cookie - arguably the most famous cookie of all time - also makes its way onto our "older than you think" list.

First invented in 1912 on "Oreo Way" in New York, the aged cookie predates even the invention of Insulin, as well as "chocolate chip cookies, sliced bread, and my 100 year old Great Grandmother" (as TheSilentShane puts it).
