Everyday Things You Didn’t Know Had a Purpose
There's a list floating around online of everyday things you've probably never thought about. But they all have a purpose.
- The hole in the top of a pen cap. It's not some weird engineering thing that keeps it from drying out. It just makes the cap less of a hazard for little kids by keeping their airway open if they choke on it.
- Sometimes when you buy nice clothes, there's an extra piece of fabric in one of the pockets. It's not there in case you need to make a patch. It's there so you can test laundry detergent on it.
- The little "fifth pocket" in your jeans was originally there to hold a pocket watch. And the metal rivets prevent the seams from ripping.
- On a measuring tape, there's usually a tiny hole in the hook at the end. It's there so you can hook it onto a nail or a screw. And the bottom of the hook usually has little teeth, so you can use it to mark drywall while you're measuring.
- There's a soft plastic disc under the lid of a two-liter soda bottle. Even if you take it out, the bottle might not leak. But it has to be there to make it airtight. Otherwise it would go flat a lot faster.
