Its actually not so much that the bubbles are floating to the top as that the water is sinking to the bottom. Since water is pretty heavy, gravity pulls it downwards. So the water thats above the bubble gets pulled down to the bottom, just like if you were to dump a bucket of water on the ground. Once all of the water is pulled down as far as it can go, the bubbles made it all the way to the top.
