The Power of Water

The Power of Water

It WAS hot. The sea glittered as though it were raining quicksilver. The waves rolled invitingly to the beach. My younger son and I decided to brave the cold water (this was Britain!) and take a cooling dip. After the initial shock, the water was wonderful, and we played in the waves for a long while. Fun became exhilaration as the rollers grew around us, picking us up like flotsam or crashing over us. We were reminded of the power of the waves as we left the water. One would carry us towards the shore whilst the next would flatten us! We made the shore perfectly safely and were elated for the rest of the day. The scientific numbers make impressive reading. A cubic metre of water weighs 1000kg, or a metric tonne. Physicists have calculated that a breaking wave will exert peressure of up to 30,000 kg per square
