Bubbles are amazing. You simply submerge what seems like a "magic wand" into a special mixture of soap and water gets lifted out of the solution and soon creates a magical multicolor translucent oval. And all this magic happens when you purchase a simple bubble mix from a dollar store, online, or by making your own bubble solution
Bubbles are so light, that they are floating. Flight would mean that they are using wings and/or a propulsion system to move.
