I hope my children don't read this blog because one of them is going to get this little car in their Christmas stocking. Well they aren't exactly children any more but they still like surprises. It's advertised as "The Worlds Smallest Mini Solar Powered Robot Racing Car Toy Gadget Cool". I just received one in the post and it really works and not just in sunlight but also if placed under a spot lamp. I thought this would make a great subject for a design lab so I'm going to order a whole bunch of them and a class set of spotlamps.

They're dead cheap and can be ordered from Ebay.
