Use a big bubble wand or make one with two sticks and a cotton string loop
Mix 6 cups water, 1 cup dish soap, and 1/2 cup corn syrup or glycerin
Let the mixture sit for several hours or overnight
Use soft, clean water if possible
Dip the wand fully into the solution
Move the wand slowly and steadily through the air
Blow gently and continuously
Avoid windy conditions
Add a little more soap if bubbles pop too quickly
Add a little more corn syrup or glycerin if bubbles are too weak
Use a wide, shallow container for the bubble solution
Keep hands clean and dry before making bubbles
