(CNN) -- Looking for a small car? Check out the sub-sub-sub
compact from Australia -- said to be the world's smallest
Scientists demonstrated how small the 5-millimeter-long (0.2-inch) car is by having it circle some Australian 10-cent coins. Roughly the size of a rice grain, the car drives itself and travels 0.36 kmh (.22 mph).
Neither the speed -- nor the size -- would be sufficient for a human driver, but that doesn't bother scientists. What interests them is how far they can take miniaturization. Miniature motors could have a wide range of uses, and the makers are reveling in this advance in nanotechnology.
