Not much vertical distortion with a long string of text

Hi - I'm trying to achieve a sort of flag waving effect on my text. I noticed the example for the liquidDistortionMaterial has quite a bit of up and down movement, but it seems when you have a longer string of text there's not a lot of vertical movement (none, really).

Is there any way to exaggerate the up and down movement? Maybe even by editing the material? Here's what happens currently:
