Today an encore presentation of an episode that originally aired on March 26th. Circle April 8th for the chance to see something you may never see again during your lifetime.  A total solar eclipse will be witnessed in a specific path through Canada on that day, and in almost all of the rest of the country, a partial eclipse will be experienced. So what to do, where to be and how to safely watch the eclipse are all good questions and today Science Sam, Dr Samantha Yammine, joins us to answer them.
