For surface tension, something different is going on. There is an interaction between the molecules in the water and the aluminum (and between other water molecules).

How? It all has to do with something called surface tension. Try this activity to learn more! Background You have probably noticed that if you look at a surface outside on a rainy day or spill ...

But soap has a lower surface tension, so there is a difference in surface tension between the areas of high and low soap concentration. This drags the water back into the film.
