Three Handles On Jerry Can
Jerrycans were created for military purposes in Germany in the 1930s. The jerrycan’s original design is still widely used in the military today. Because it was requested that a soldier should be able to carry two full or four empty containers by holding onto the outer handle, the three handles were constructed. Three handles go across the top of the container to keep the fuel properly spread while you hold it.
This is particularly true when it is carried by two people. If you’re carrying it with a friend, grip one of the outer handles for each of you. If you’re Hercules enough to carry it alone, take it by the middle handle, or by the outside left and right handles, respectively, if you’re holding two in each hand.
Brass Doorknobs
We don’t expect you to notice brass doorknobs, so give yourself a break on this one. Brass is used for every doorknob. The doorknobs are constructed out of this for a very good purpose, and it’s not by chance. Brass objects are more resistant to the growth of bacteria. Consider how frequently doorknobs are touched during the day.
The brass helps in keeping them germ-free. This is critical, given that individuals frequently touch doorknobs after handling a variety of other objects. People will take up germs on their hands in a number of ways, so this is obviously crucial. We are less exposed to germs because of the brass than if they were made of another material.
