ive done this since i was little. if you have a bubble sitting on flat surface blow on it very lightly so the rainbow colors swirl. then if you stay real still its when the bubble loses color (i say black) it pops. I asked a chemistry teacher this and he said there was an experiment on this but i cant remember the name. something about light and the rainbow. cant fine full explanation.

After you blow a bubble with soapy water, the film of soap/water that makes up the bubble grows thinner.
The color you see depends on the thickness of the film, as it relates to the wavelength of different colors of light. Just before it bursts, the film is so thin that its effective color is outside the color spectrum that humans can see (you would probably see swirls if you could see in ultraviolet).

surfact tension created by the soap in a bubble is no match for gravity. Gravity pulls the liquid toward the bottom of the bubble but this thins out the surface of the bubble and it becomes even more transparent than it already is. The bubble loses color because there is not enough material there to refract the light.

never seen that happen before

well, once you go black, you never go back
