Let’s face it — that little hole in the center of plastic stools has puzzled many. We’ve all sat on those stools at parents’ homes, tiny tea shops, food stalls, or outdoor weddings. Yet, few know why that hole exists. Is it a design mistake or something clever? Spoiler: It’s surprisingly smart.
Breaking the Suction: Easy Handling and Stacking
Have you ever struggled to separate stacked plastic stools? Without the hole, the stools create a vacuum seal, making them stick together like a stubborn Jenga tower. The hole lets air in, breaking this suction. This simple physics trick makes stacking and unstacking easier.
Plus, the hole doubles as a built-in handle. You can grab and move the stool effortlessly. Who knew stools had ergonomic features?
