The Washing Machine

Another Birthday of a very important invention, The Washing Machine. Go ahead and pile in those smelly socks, panties, or underwear 'cause when they come out you know they'll be clean. So go ahead and tell it you love it. It makes some lives so much eaiser! 1797 Nathaniel Briggs of New Hampshire patents a washing machine
