Question: How do you get your kids interested in green issues? Answer (well one answer anyway): Buy them an inexpensive robot building kit of course!
Not only does your child get to build 6 different robotic masterpieces - including a dog, a boat, a windmill and a car - but also gets to learn about solar energy in the process. All the instructions are easy to follow and the kit only has 25 parts to it. The best bit - no screws in sight! Oh, and don't worry that the UK's lack of sunlight might spoil your kids' enjoyment as the solar charger can also produce power when exposed to a bright halogen lamp. [Paul Ridden]

So, where can we get one smartypants?
Ah I see that you spotted my deliberate marketing ploy - the kit can be bought from:
