First start by making a Capsule. Objects>Primitive>Capsule.

Make the settings like I have shown below. Then click Apply.

It should now look like this.

Duplicate the capsule (copy and paste). Make the coordinates of the duplicated capsule (Capsule.1) look likes the settings shown here. Then click apply.

It should now look somewhat like this.

Now apply Boolean by doing this...

Or another way is...

Now put both Capsule.1 and the orginal Capsule into Boolean.(Make sure the original Capsule is ABOVE the duplicated capsule!).

Now your image should look somewhat like this.

If you dont like the way that looks, just move Capsule.1 forward or backward. (USE THE GREEN ARROW!)

I changed the coordinates for Capsule.1 to... and then applied them.

If you use the settings above, it should now look something like this:

Now just goto Render>Render veiw to see what you got.

I added some materials, a plane, more boolean bojects, and lighting. I then came up with the below render.

It may be a bit sloppy, but add some hyperNURBS( Objects>Nurbs>HyperHURBS) and you can make some renders that look great.
