My 12 year old son could do a little better in science and I thought it would be cool to get the "Bill Nye the Science Guy" vids. I always liked them. I figure that maybe if he watched them, science would be a little easier. So I google. Disney want $2000 for them!!!! That's not gonna happen. So I look on e-bay: 1 at a time goes for $10 to $20 each, but you will probably never get the complete set. Any suggestions?
