Have you ever wondered if lightning can strike twice or if Stress can Turn Your Hair Gray? A lot of us have questions that usually require a whole bunch of scientific language to answer and while that works for adults it is usually not the most useful thing when trying to explain things to a kid. Keeping that thought in mind the Smithsonian has created short videos (about a min in length) that answer such questions in plain English. Check them out at the Ask Smithsonian video archive.
The best part is that you can also submit your questions to the site and if selected a video with the answer would be uploaded to the site. Some of the questions that are currently answered on the site are:
Ask Smithsonian: Does Chicken Soup Really Help With a Cold?
Ask Smithsonian: How Do Noise-Canceling Headphones Work?
Ask Smithsonian: Why Don’t People Smile in Old Photographs?
