If you’d like to halve the recipe, pour just 2 cups (470 ml) of warm water into a jar and halve the remaining ingredients. For bubble solution that lasts longer, use distilled water. If you’re not concerned about storing the solution, it’s fine to use tap water.
If you’re using a sealable jar, screw the lid on tightly and shake it until the sugar dissolves. Sugar sounds like an odd ingredient to add to bubble solution, but it binds the ingredients together so your bubbles and solution last longer. If you don’t have any sugar, you can leave it out, but it will be harder to blow bubbles.
If you can’t find glycerin, use corn syrup instead. Corn syrup acts like glycerin to slow down evaporation, so your bubbles are stronger and last longer. [5] X Research source
Throw out the bubble solution if it looks cloudy or begins to smell bad.
Keep in mind that the food coloring will mix with the original color of the dish soap. For example, if you add red food coloring to blue dish soap, you’ll get purple! Use clear dish soap if you want to make yellow, orange, or red bubbles.
For instance, if you’re using lemon dish soap, add lavender essential oil to make a lemon-lavender-scented bubble solution. Avoid adding more than 15-20 drops since essential oils are very concentrated!
