24 Features On Everyday Products That You're Not Using Right

Here's the reason: The stick is hollow so that any child who accidentally swallows the stick won't choke to death. And as for the hole, it's there to hold your sucker in place. Without it, the ball-shaped candy on top would just fall right off the stick. During production, a bit of sugar paste is added into the hole, which helps keep the sucker attached to the stick.

Its actual purpose is more straightforward: The small hole lowers the risk of suffocation if, for example, a small child accidentally swallowed the lid.

It's purpose: That black strip is called a "frit" and it essentially has two purposes. It provides an etched surface for the adhesive to adhere to, which bonds the glass to the frame. And on the outside of the glass, it protects the adhesive from ultraviolet light and covers any unsightly adhesive. The dots are there just to make it look nice.

Yep! Here's what it's for: Unscrew lid, turn it around, and use the point to pierce the foil covering on most tubes of medicine.

Here's what it's for: When jeans were first invented, back in the days of the Wild West, the fifth pocket was utterly indispensable. Because it was the place where cowboys and gold diggers kept their pocket watches.

It's simple: They're there to strengthen the trousers at their weakest points, and help prevent wear and tear.

The explanation: These are called eye marks. On the production line, they allow optical sensors to recognize where a package needs to be cut, folded, or pressed. The color of the eye mark is largely irrelevant, it just needs to be dark enough for the sensors to see it easily.

Here's the reason: It's called a lash tab, and it's there for you to attach whatever you'd like to your bag. For instance, a hiker could lash a sleeping roll to their bag using the lash tab. Originally, it was added to bags to carry tools like axes.

The simple reason: According to Heinz, this is the "sweet spot" on glass Heinz bottles. If you tap with your palm on that spot, then the ketchup should come out more easily. So, stop banging on the bottom of the bottle.

Here's how to use it: The arrow points to the side of the car your gas cap can be found on. If your car is older, or doesn't have an arrow, the direction of the fuel hose sometimes indicates where the gas cap can be found.

Actually, the reason is quite simple: Many hairpins have a grooved and a smooth side. The grooved side is meant to face in towards to scalp to provide a little extra hold.

Their purpose: These markings are the tread wear indicators. And as the name says, they tell you whether a tire worn out or not, depending on how close they are to the surface of the tire.

Here's what the non-sharp side can do: Utility knife blades often have perforated blades that can be snapped off when the cutting edge gets too dull. They also have a little slot on the very back of the handle that you can slip the blade into to snap it off cleanly and easily.

Here's the real reason: You probably thought the little swatch was meant for patching holes or something, right? Nope! (Well, possibly, but not primarily.) They're actually there so you can test how the fabric reacts to different detergents.

That's an easy one: It's for hanging up the ruler.

Here's an explanation: They're sometimes called orientation keys, and they're there for people who have mastered touch typing. Those keys are in the home row, and your index fingers rest on the F and J keys when they're not typing.

There's two possible explanations: First, they're there for ventilation, especially if you're not wearing socks. But some people also claim that they can be used to lace the shoes even tighter.

This one is pretty cool: It's there to let pasta water strain through, obviously. BUT ALSO, on many ladles the hole happens to be just the right size for one serving of uncooked spaghetti.

Again, it's multi-purpose: The original and most obvious use is for hanging your pots and pans when they're not in use. But you can also use the hole to hold onto a saucy spoon while you're cooking.

Huh? No bull! if you've got a screw that's too tough to reach, you can slip the box-end of a wrench over the handle of a screwdriver to give yourself a bit of an extension.
