In this English lesson I'll help you learn about some the greatest inventions! Interestingly, the names of many inventions are also used in idioms! Do you know what it means to "put something under the microscope" or what the "greatest thing since sliced bread" is? You may have already learned some of these in a previous English class or they may be new to you.Either way, join me for what I think will be a lot of fun as we learn some English together.In this English lesson I'll be sure to help you learn many English vocabulary words and phrases about inventions.I hope you enjoy the lesson!Note: This is the audio portion of a Youtube English lesson which you can watch right here: https://www.youtube.com/watch?v=ei_TeDDYwU4 or find by searching Youtube for, "Bob the Canadian Inventions".Support the show (https://www.patreon.com/bobthecanadian)
