Hand held torch, GOOD sewing needles, (small) pliers, and one of mothers good kitchen spoons. Pressure up the pipe, heat the needle red hot and make your orifice. Those which are too big (most will be) adjust with the red hot back of the spoon. You can seal the spray with the spoon also when you realize you made three times too many openings! This method does not clog nearly as bad as the commercial misters.
