Two years ago I invested in the Popular Mechanics for Kids (PMK) 24-episode-DVD-set, and it was worth every penny! The point of the show is to teach the viewers how things work, whether it be rockets, or roller coasters, or sea creatures, etc. The show entertains and captivates my children, while providing them with some knowledge on the subject matter. I cannot begin to tell you how many conversations I've had with my children that sound something like this.....
Child: Hey Mom! Did you know komodo dragons don't chew their food, but swallow hunks of flesh whole.
Me: Where did you learn that?
