Welcome to science at home in this experiment we're creating giant bubbles using a guar gum giant bubble recipe. Guar gum is a natural polymer and will help to give the giant bubbles a better longevity and self healing properties. Bubbles will always try to stay in a sphere shape. This is because a sphere shape needs the least amount of energy to achieve and keeps the surface tension even. When a bubbles stretches and shifts the Maragoni effect shifts the soap in the bubble to weaker areas to prevent the bubble from popping and tries to keep the bubble spherical. The bubble recipe in this episode will allow you to blow giant bubbles that can be 40 feet long or more at times. By the end of this experiment you will be able to explain why bubbles are spherical, what a bubble is, what a bubbles structure looks like and how to make giant bubbles at home..
