ok first just try to get the water in a cup waving. first put your hand in the cup fell how the waves feel then take your hand out and imagine how the waves on your hand felt while imagining this focus on the qwater. thats a pretty basic technique.

next drop a small object in the water watch at how the water lifts around i then were it was try and duplicate this with your mind. after that just try to lift the water in one spot, no not even lift just try to make it buldge up and try to make it buldge inward.

if there two easy im sorry they're the two that i've been trying .
