Holes In Padlock
Padlocks are useful for a variety of reasons, and you’ve probably used one at some point in your life. Have you noticed the padlock’s bottom has a little hole? As you might have guessed, these holes are useful. The holes are there, first and foremost, to drain any water that has entered the lock. If this is not possible and the water cannot drain, the lock may freeze, causing serious damage.

Another use for these holes is to allow you to pour oil or WD-40 into the lock if it becomes jammed and refuses to open, rendering the item worthless. So, if that treasure chest you dug up as a kid has been stuck for years, you now know how to unlock it and recover the treasure! However, we do deserve a share of the gold.
Hole Next To iPhone Camera
If you have an iPhone, you’ve probably noticed a little hole next to the camera lens. If you’re like the majority of us, you probably didn’t notice because you’re more likely to use the selfie cam. That little hole isn’t a second secret camera that helps Facebook and the NSA spy on you, in any case. It is, in fact, a microphone.

All iPhones have had three microphones since the iPhone 5 was released. One is placed directly beneath the speaker grill, another is placed on the phone’s bottom edge, and the third is positioned near beside the camera lens. It’s easy to pick up sounds thanks to the three microphones included, regardless of how you hold your phone.
