🔨 Car headrests aren’t just designed for, well, head-resting…
Headrests are made to be adjustable to comfortably support a person’s head. Duh! But why make them completely detachable too? So your kids can have weapons to fight each other with? Nope! They’re detachable to help you survive. When you pull your headrest out of the seat, it has two sturdy, long metal bars, correct? Well, that’s so if yourself trapped inside a car and need to get out quickly, you can simply detach your headrest and use it to smash out the window. 🔨
😈 Coins have ridges because of some really shady characters…
While the ridges on coins make them easier to grip, that’s not what the ridges are for. Actually, those ridge patterns are a relic of the past, when precious metal coins would be literally worth their weight in that precious metal. (Meaning, a $1 piece would be a $1 worth of silver.) However, some nare-do-wells saw an opportunity to make a killing by shaving off the edges of coins, selling them for face value, then melting down the shavings to sell or mint as new coins. Sneaky, though it does sound tedious. 😈
🚑 The holes in pen caps…
Why are there holes in pen caps? Because the manufacturers know you’re going to chew on them, that’s why. See, you’re not SUPPOSED to chew on pen caps, because they’re a choking hazard. But if you do, and accidentally swallow one, the hole is there to help you keep breathing while the ambulance is on its way. 🚑
