Detachable Headrests
While the fact that most cars have adjustable headrests is quite logical as you may need to adjust the height for comfort. However, you may be puzzled as to why headrests are also usually detachable. The answer is both to be adjustable, to make it easier to clean, and most unexpectedly, to break a window using the metal bars in case of an emergency! This final point is essential to remember, just in case you ever find yourself trapped in a car and need to make a speedy exit.

Handles On Jerrycans
If you love outdoor adventures such as camping trips jerrycans are extremely handy. However, you may be wondering why there are three handles on top of these containers. The cans are designed like this to ensure the fuel inside is evenly distributed while carrying it. If you are carrying the can alone, you should use the middle handle, if you are carrying two cans in one hand you can use the side handles, and if with a friend each person can grab a side handle each. This design was crucial during the second world war.
