Weegy: Nearly everyone has enjoyed playing with soap bubbles. These fragile spheres of soap film filled with air are both beautiful and captivating. [ However, few people have observed them closely or at length, because soap bubbles are fragile and very light. When you blow soap bubbles out of doors, the slightest breeze carries them away. If you blow them indoors in still air, the bubbles soon settle onto a surface and break. However, because they are very light, soap bubbles will float on a gas that is only slightly more dense than the air that fills them. Such a gas is carbon dioxide. When soap bubbles settle into a container of carbon dioxide, the bubbles float on the carbon dioxide and can be examined closely. Under this close examination, soap bubbles reveal many properties that are not otherwise easily seen. To float soap bubbles, you will need the following materials: * soap bubble solution * a wand for blowing soap bubbles * a large transparent container with an open top (an empty 38-liter [10-gallon] aquarium works nicely) * 125 milliliters (½ cup) of baking soda (sodium bicarbonate) * 250 milliliters (1 cup) vinegar * shallow glass dish to fit inside large container (such as a glass baking dish) Set the large container on a table away from drafts and where you can easily look through its sides. Place the glass dish inside on the bottom of the large transparent container. Put 125 milliliters (½ cup) of baking soda in the glass dish. Pour 250 milliliters (1 cup) of vinegar into the dish with the baking soda. The mixture of soda and vinegar will immediately start to fizz as they react and form carbon dioxide gas. Carbon dioxide is more dense than air and so it will be held in the large container as long as it is not disturbed by drafts of air over the container. Because carbon dioxide is colorless, you cannot see it inside the container. ]
