how does a water bubble seal itself?

when one mixes water and soap and with the help of a pipe creates a bubble, then one can observe that as soon as the bubble comes free of the pipe, it seals itself on the spot where just before the pipe flowed into it. this occurs because water always attracts other water and thus one side of the bubble’s opening migrates to the other side.
