Learning by questions Q1

My son asked a question in the car today. He asked, “when was the first radio made?” I told him that he should do some research and come back and tell us when the first radio was made. The next video that we make will be him explaining to you what he found. Feel free to leave your questions here so that he will have more research to do. This is a great way for him to learn and I thank you for your assistance.
