Do you know this .
When you throw stone on water surface with revolutions at angle of 20 to 25 degree , stone will bounce on water twice or thrice or even more . It's rotation cause these bounces .
In America they held championship of stone skipping .
It's kind of fun and amazing mechanism to watch.
Can you imagine that this technique might be used to build the bomb ?
Yes it was.
During second world war Britain was facing heavy air attacks from Germany . To stop those attacks they will have to destroy their production line . Which was secured with anti aircraft gun and Radar . Generally these machinery industries require lots of water . To fulfill the need they built their industries near the dams .
In order to destroy the aircraft industries Britain need to destroy these dams.
- Möhne dam
- Eder dam
- Sorpe dam
- Ennepe dam
But it was too much difficult as all these dams have anti torpedo nets protecting it from any attack .
To destroy it one need to blast the bomb at the base of dam .
Britain developed special bomb for this named “bouncing bomb” which was invented by Burnes Willis .
Its shape was like drum . Its weight was around 4000 kg . It's released at Target with 500 rpm . This will help to skip on the water . And after reaching to the wall of dam it's revolutions help it to stick to the wall . This bomb now acts as a depth charge . After reaching to certain depth it will blow up.
Britain was successful to slow down German aircraft production by attacking with these bombs .
It had a great impact on WW2.
