Use a funnel or spouted measuring cup to carefully pour the water, dish detergent and light corn syrup into the rinsed out jug, or simply measure out and pour it into a large bowl.
Place the lid on the jug and tighten securely. Generously shake the jug to mix the ingredients. If using a bowl, whisk the ingredients using a fork or whisk to thoroughly mix the bubble liquid.
Pour the bubble liquid into a shallow pan or tub so it is easier to dip the wands into the bubble liquid.
