'''Comparison of thick and thin skinned bubbles. '''The videos below were created in the same conditions with bubble juices that create very different initial film thicknesses. The video on the left shows a thick-filmed bubble. Notice that the colors are initially dominated by the pinks and greens associated with films 700 nanometers and thicker while the thin-skinned bubble starts off with some areas as thin as 100 nanometers (as evidenced by white spots). Another interesting characteristic of thin-skinned bubbles is the tendency for the initial color swirls to continue longer than they do in thick-skinned bubbles. Note: I am blowing on the bubbles which shortens the lifespan due to evaporation and stress. Under less stress, the difference in lifetimes would be even larger. |

Critical dilution. In some dilution ranges (usually low dilutions) changes in detergent concentration have less of an impact on the film thickness than on others. In this case, the films are usually pretty thin to start with. |
