What do you call it when drops of water seem to reach toward one another when combining?

Question

When liquid drops on a surface combine, there is that moment when multiple drops seem to reach out to one another. Does this phenomenon have a name in physics?

You can see it at about 3:15 in this clip from T2. http://www.youtube.com/watch?v=e5gGV1WB-xg

Silly example, but it illustrates the basic idea.

Answer 1

coalescence ?

Answer 2

It's called either cohesion or adhesion. I think cohesion is water attracted to itself and adhesion is water attracted to something else, like glass when it forms a meniscus but I might have that backward.

Answer 3

I call it awesome.
