Kardtects loves to share fun and interesting facts with readers about buildings and architecture.  This following fact is about doorknobs.  Although maybe not thought about often or realized, doorknobs are made out of certain metals, like brass, for a very good reason!  That reason is that brass doorknobs naturally kill and resist germs.  How cool is that?

Certain metals, like silver, copper, brass, or aluminum are antimicrobial.  And since doorknobs get touched a lot, by many different, and these people are sometimes germ carrying people, what better way to help protect against passing germs from one person to another, than to have a brass doorknob?  It seems on the frontline of battling and fighting off sicknesses are the doorknobs to buildings!

So the next time you are turning a doorknob or pushing on those brass plates to open doors, know they are doing more for you than just offering entryway or looking pretty. They are fighting for your health!  😊

Kardtects is classic fun with a modern twist.  Master the Build!
