School boy experiment with water

@TinselKoala,

1) I  have done that experiment completely and after confirming I have posted that expriment here.    I think you have just filled the balloon with water and dropped it into water container.   With that you cannot make out anything.   Fix a lengthy vertical tube into it and repeat the sequence which I have said in my earlier reply.   
2) I am not making use of the energy stored in first  place while filling  the water  but by  moving the water balloon up and down inside the water container.   The energy stored in first place stretching the skin doesnot come into picture here.     The stretch of the skin varies  ( gets compressed or expands)  depending on the depth to which water balloon is pushed inside the water container. (only if you fix a vertical tube to the balloon)
I cannot explain anything more than this.    I am retiring from the argument.
Thanks anyway for the nice discussion.

Regards,
Vineet.K.

so how can we close the loop here? how would you feed the output back to the input? how would we make this self running?

vineet_kiran,
Any news on this experiment?

This seems to be a interesting experiment.  I tried experiment several times each time with a different diameter tube and also at deeper depths.  I didnot experience much input force in any of those trials.


Since parameters on both sides of the tube are identical,  you will not experience any force even if you use larger diameter tube and go to a higher depth.  I think you are making use of potential difference existing at two different heights of water. (mgH2 - mgH1 ?)
