Skewing the bottom of a spray of water?

I want to make it appear as if water is spraying from an open hole on the top of a container. I found a video of spraying water and placed it above where the hole is located.  I created a mask to limit the part of the video that displays of the water, and I changed the blending mode to lighten to remove the background so only the spraying water displays. 
 

the base of the water where it is starts small and turns into the giant spray is too wide. I want to transform the base of the spray to make it seem like it is smaller and actually coming out of the opening on the container. I tried applying a transform effect to it and I played with skew but that doesn’t seem to get me what I need. How is this done?

Thanks in advance
