If you enjoy Feynman's lectures as much as I do (he taught freshman physics when I went to Caltech!) I highly recommend his armchair series, "Fun to Imagine":

He's sitting at home in Pasadena, talking about stuff that comes to mind.
• Jiggling atoms who like to make friends with each other.
• Where do trees come from? (It's not the dirt.)
• Why don't your arms sink through the armrests of your chair?
• How do trains stay on the tracks?
It's an hour of fun science, and especially accessible for anyone who is curious about physics but doesn't enjoy all the equations.
