   A rhino's horn is made of keratin, the same material as your hair and nails, not bone.

3. A racing greyhound 76 km/h

   Greyhounds reach their top speed in just a few strides and spend much of a sprint completely airborne.

   The Cessna 172 is the most-produced plane in history and the trainer that taught millions of pilots to fly.

5. A record tennis serve 270 km/h

   The fastest serves leave the racket so quickly the returner must react before the ball has even crossed the net.

6. A meteor entering the atmosphere 50K km/h

   Most shooting stars are no bigger than a grain of sand, burning up bright from sheer speed alone.
