A long time ago I was doing a competition to take an aerial photograph using only some bits and bobs from a hardware shop. We were in rural countryside, and the other groups all came up with a design that involved a mechanical hammer to hit the shutter release. I came up with the idea of a magnet which would be released by an electric switch. We would send the camera up on a kite using electric wire as the kite string, all attached to a switch. Hit the switch, the magnet drops hitting the shutter release. It was great fun haring over the countryside looking for shops which would sell us the parts (on a sunday morning nearly 30 years ago). And the best bit was that we took by FAR the best picture!!!!

   Mình viết về vấn đề lũ lụt nha:

    Floods are a natural phenomenon. They cause tremendous havoc to human life and property but are sometimes also a blessing in disguise because they bring alluvial soil which is essential for crops. This is a great benefit compared io the havoc it creates. Floods are naurals calamities nad occur regularly in certain low lying area. The unexpected flood causes great misery. The rush of water demolishes houses and destroys homes. It inundates large areas under cultivation, wrecks public services and makes the life of the surviors miserable. Sometimes man is prepared for it and has learned to take advantage of floods to enrich their soil, trap fish and more logs of woods. Floods, however have always brought out the best in men. Men organise recus and relief activities for strangers without expectation of personalgain. Voluntary organisations organise relief camps and provide medical facilities. Floods bring out the best in men to the surface. People throughout the world make collections and airlift relief materials to the victims. The increasing incidence of floods can be reduced by contruction of damsand catchment areas. These activites can't be carried out by a single man, but can be achived only by thr Government as these require colossal resources, organisation and manpower. Every single man can contrinute to pevent foold by planting trees and preventing denudation of vegetable plots. Forestation is one of the best alternatives to alternatives to arrest floods.
