Rearview Mirror Tab
Keeping an eye on the rearview mirror is an essential part of driving. However, when you are blinded by the headlights of the car in front of you, it can be difficult to do so safely. If this occurs, you can simply pull on the tab at the bottom of the mirror to remove it. The ability to modify its location and see what is happening behind you is provided by this feature.
Coin Ridges
Those of you who have wondered why quarters and dimes have such rough edges are in luck because the answer is here. It was customary in the past to stamp coins with weights that corresponded to their true value. The edges of coins were used to be shaved off before they were given the ridges. People would then use the shavings to manufacture new coins!
