1 Tbsp dish soap, 1/4 cup water, 1/4 night rain glaze, mix, put straw on cup with solution and blow onto same until bubbles billow out and drape over piece. I wasn't sure the blue would show up well so after the fact I added a squirt of the kiwi underglaze on top of bubbles in cup and lightly mixed and the blew into straw again and draped more bubbles especially to the inside and that is why they are much more defined at the bottom of the cup
