My husband and I flipped houses for a number of years, and we made some pretty wild discoveries when ripping apart old houses. Some of my favorite finds include a wad of old bills (many of which are actually fairly valuable now) hidden within a wall, and hundreds of old glass bottles from the Prohibition stashed underneath the floor of a house. But we have also come across a number of homes that feature the oddity I’m going to talk about today.
Old homes (I’m talking in the 100-year-old range) will sometimes still feature their original medicine cabinets in the bathrooms. On the back wall of the cabinet, you will sometimes see a small slit right there on the wall. You may have noticed this in your own home or in someone else’s home, but never knew what it was for.
