Step three:

Now lets add a shatter effect. First we have to modify the eraser brush so its shaped randomly. Set your eraser to a 13 px hard brush and add the brush shape dynamics settings found below. To access the brush presets go to windows > brushes. All you have to do now is erase to get a shatter effect your looking for.

Brush Presets Shape Dynamics Size Jitter: 55% Control: Fade & 70 Minimum Diameter: 11 Angle Jitter: 9 Control: Off Roundness Jitter: 35 Control: Fade & 25 Minimum Roundness: 23

Step four:

Lets apply the same technique to a text. First type in your text in #000000.

Apply the same layer-styles from step 2.

Finale:

Now add a shatter effect, use the same technique as step three. The more random the shatter effect looks the better it turns out.
