1. Do you know why some suckers have hollow sticks with holes near the top?
2. Have you ever noticed the little metal plate on your stapler before?
Its purpose is simple: Nearly every stapler has two functions! The more common setting bends the staple back onto itself, ensuring that your papers will be held together tight. But if you rotate the base plate, the staple will bend outward, which is meant to be used for a looser hold that you can more easily remove later.
3. And do you know how to read these codes on your makeup?
Here's what they mean: On the back of your makeup products, you can often find numbers like: "6M", "12M" or "24M". They represent the life of the product on your shelf after opening. So in the above example, you have about 12 months to use this face cream before you should think about throwing it out and replacing it.
