Doh! I shoulda used CDs for the can racer!
Remember my coffee can racer from a while back? Well from GeekDad I got to a site where you can put all those dern, unrecyclable CDs to good use…turn them into racers!
Man I wish I had found that earlier, cause how many kids get to race a car with wheels made from beta builds of Ubuntu!
