Rearview Mirror Tab
As a driver, it is part of your job to look in the rearview mirror regularly when you are on the road! However, have you ever taken the time to notice the tab at the bottom of the mirror? Not many people know what it is for. It turns out that it allows you to change the position of the mirror to prevent getting blindsided by lights from behind you. It deflects the light and allows you to see what is going on.
Coin Ridges
Have you ever noticed the fact that quarters and dimes both have rough edges? You do not find these features on pennies and nickels! Go ahead and check the coins in your purse if you are not sure. This is actually a remnant of the period in history when coins got stamped in different weights to reflect the real value of the coin on hand. They wanted to stop people who shaved off the edges of the coin to make new ones! The ridges were made of precious metals to ensure that this no longer happened.
