Will a Vacuum-Sealed Bottle Move Forward or Backward When Opened Underwater?

[basheer uddin]

If we create a high vacuum in a bottle and immerse it in water and then open the cork.which way will it go ?
will the bottle move backward (towards the nozzle) or forward?

 

[DaveC426913]

It will jump "backward" (towards the nozzle), then stop.

It will move in the direction of its opening.

 

[basheer uddin]

Ok i get it! the water pressure pushes the base and there is no opposite push on the other direction. right?

 

[basheer uddin]

what if there is an infinite pipe instead of a bottle?

 

[ambarishsr]

Right... (y)

 

[ambarishsr]

How would you immerse an infinite pipe?

 

[DaveC426913]

And how long would you wait for results? Movement would only propagate at the speed of sound of the material.

How would you immerse an infinite pipe?

In an infinite pool. You can get both down at the Ideal Hardware Store.

Put a pail of water with a bubble in the middle in the paint mixer at the right freq, and you can see your zero dimensional sonoluminescent "bottle".
