Drop your jaw slightly with relaxed lips. Touch the tongue tip behind the bottom front teeth and arch the top-front toward the roof.

Americans pronounce its as ihts (/ɪts/). In fast speech, the vowel in "its" vanishes — the "ih" is completely elided, leaving only a quick "ts" cluster — this is a feature of casual, connected speech; in careful speech, the vowel is retained. This is called the Short Contractions (it's, that's), how Americans collapse little words. It comes out as ihts. You'll hear it in sentences like "It's a small world after all" or "It's a beautiful day, isn't it?" — more examples below.
