How to make bubble solution at home:
1. Pour 4 cups (950 ml) of warm water into a large jar, distilled water would be better.
2. Add 1/2 cup (115g) of granulated sugar, then stir until it dissolves.
3. Stir in 1/2 cup (120ml) of liquid dish soap.
4. Wait a few hours before you use the bubble solution, it would be even better if you wait until the next day.
Note: If you make bubble solution by yourself at home, store the bubble solution in a cool, dark place, like the fridge. Use it within a couple of weeks.
