If you want to add more details to the bubble, you can add an
image texture in the Node Editor panel and import an image
that gives more imperfections to the material. This node must
be linked to the Glossy BSDF Shader in roughness.
In the Node Editor panel, you can add shaders, converters and many other elements that will
help you in the creation process of a material
