In South India, there are people who claim that they can measure the underground water level by using the coconut.
They will hold coconut in their palm and walk on the site. Near the water source the coconut moves upwards, defying the gravitational pull and thus mark the spot for digging bore well.
I have witnessed this and the place they marked got abundance of water after digging.
I wanted to know is it true that we can measure water level by using coconut or is it just a phoney trick. If it is true, how it can happen? Is there any scientific explanation for this?
