What do you notice in the bubbles?
How could you make a bubble inside another bubble?
Can you make bubbles of different shapes, sizes or colors?
Why do some bubble last longer than others?
Add 5 tablespoons glycerin or 1/2 cup corn syrup to make bubbles last longer.
Add 1/4 teaspoon guar gum for giant bubbles. (mix guar gum with glycerin or corn syrup first to prevent clumping)
Mix ingredients together slowly to avoid making bubbles in the solution.
Bubble solutions are best after they rest over night.
