In this tutorial video for Unreal and Unity, we learn about iridescence and what causes it. Then we use those principles to create a realistic soap bubble shader that use Fresnel for opacity and animated membrane thickness to control how the iridescence is applied.

Here are some additional resources for learning about iridescence and bubbles:
