That tutorial is an express tutorial about how to make a bullet trasversing a liquid sphere with Blender 3D. You'll have to know a little bit how to use blender because I will not explain everything.

This is a very simple scene with only a sphere, a cube, and a bullet.

You should know that there's different type of Fluid (fluid, inflow, outflow, domain, obstacle, etc ...)

At first, you'll need create a sphere (it will be the water fluid), a cube (it will be your domain), and a bullet (it will be an obstacle). You can see the scene on figure 1.

The for each of the object, put these tweaked (not specially the best, but worked) settings like in the figure 1, 2, 3

The Bullet fluid settings -  Figure 1 

The liquid sphere settings - figure 2

The domain settings - Figure 3

Another thing to do is to to put gravity to 0. To do that, you'll simply need to go to the 'Scene tabs' and put 0 for each value of gravity. Like in this screens

Now you need to make the bullet traveling in time and sphere :). Just put a keyframe for starting position, and another for ending position later in time like in this screenshots. You can of course tweak the IPO curve if you want ...

Normally if i didn't forget something you can bake the result. (Reselect the domain and go to the fluid settings). Press on Bake (Take a look at the memory required in order to no kill your computer :D)

Here i choosed, and 0.200 value for end, to have a slow fluid, if you play with this, you'll see a difference with speed of the speed (if I can say it ...).

After a quick (or long) bake, you'll normally see the nice result by pushing the play button to see the animation....
