| Place a bowl on a surface that is firm, but will allow the bowl to vibrate. A damp, folded bath towel or most non- slip mats make a good base. Fill the bowl about halfway with clean water. |
| Wash you hands thoroughly,ensuring that your hands are completely free of any oils.Also clean the handles of the bowls thoroughly with isopropyl alcohol.(This is especially important before using it the first time) You will not be able to work the bowl with even the smallest amount of oil or lotion on your hands or the handles of the bowl. |
| Moisten your hands slightly by dipping your palms into the water. |
| Your ability to control the bowl will inprove with practice. Try to make long, steady strokes using your whole hand, from the tips of your fingers to the heel of your palm. Also,trying varying the amount of downward pressure you use. A light touch seems to work better.With practice, you should have water spraying 50cm(about 20inches) out of the bowl. |
