Mix 1 cup dish soap with 2–3 cups water
Add 1–2 tablespoons glycerin (optional but helps bubbles last longer)
Stir gently to avoid foaming
Let the mixture sit 10–15 minutes
Test with a bubble wand and adjust:
If bubbles pop fast, add a little more glycerin or soap
If bubbles are too foamy, add more water
For a stronger solution, use 1/2 cup dish soap + 1 cup water + 1–2 tablespoons glycerin
