Bubble dynamics over a liquid surface

[Anakratis]

Hey all,

Interestingly enough, I was actually recently feeding some ducks at a nearby pond when I noticed a cool phenomenon that I couldn't explain myself, so I was hoping you guys could assist in that.

When you have two air bubbles over a liquid surface, like water, they seem to accelerate towards one another once they get close enough. Could anyone explain why this is?

Thanks! :)

If I understand you correctly, the bubbles perturb the water surface similar to the "Cheerios effect"
