I saw the video for "Electic Car" played endlessly on the Playhouse Disney chanel, and thought it was really catchy. My kids (boy 5, girl 2) would stop whatever they were doing and come and sing along with it. The vid is shown as a way of advertising the CD "Here Comes Science". I looked on You Tube at some of the other stuff on the CD/DVD, and showed my childre, and they loved it. They were so excited when it arrived. Lots of the songs are excellent. Some of the songs do not produce the same excitement in my kids, so that's why it is only four stars, not five. But still, a great purchase. Fantastic videos (great animation) and really entertaining.
