Why can soapy water blow bubbles?

Because soapy water can form a soap film, the soap film is not easily broken. When you blow air, the soap film will expand little by little and turn into soap bubbles.

Why are soap bubbles in the sun colorful?

Because sunlight is a composite light composed of seven monochromatic lights: red, orange, yellow, green, cyan, blue, and violet. If the two reflected red lights offset each other somewhere on the soap film, it will appear at this place. Less than red light but blue-green. In the same way, in another part of it, a certain color of light is intensified, showing another color.
