In mid January I bought myself a belated christmas present. It was a model to make up and it was discounted at a large chain of electronic stores. I keep them for a while, then chuck them out. My last was a sports car and the previous one, The Eiffel Tower. This one has a motor in it and you can alter the gearing by changing the rubber bands to different pulleys. The o/s rels watched me assemble it with some bemusment. I can by so immature at times. It can go very fast on a smooth floor, until it smashes into a wall, but I can't get it to hit hard enough to break it up.
