Is Air Dragged into Water When Using a Spoon with a Hole?

[bhpv]

Hi,

If i use a spoon with a hole in it in a cup of water, bubbles emerge. Does that mean that air got in?

Regards,

Water can contain disolved oxygen so could just be that. You haven't really given us much info.

Isnt that impossible? Simply mixing something in water does not bring chemical reactions into place. Also not putting oxygen together. Or do you mean water with bubbles?

I mean normal water at the kitchen sink.

Agitation (eg stirring) is a good way to release disolved gasses. Try shaking a can of soda before opening it.

Ok, if there is reaction to agitation, this is chemical. I try to see how 'big' bubbles come into existence by say stirring with a kind of stick.

Cavitation?

Edit: Perhaps I'd better explain... When an object is dragged through water you can get a pressure reduction behind the object. This can cause air to be dragged down into the water.

If not that then I suggest you post a video.
