Its interesting that when bubbles form on a drink or something, they always pop up and condense in the same places.
Also, just looked it up a bit, bubbles float because the air trapped inside is lighter than co2. Bubbles eventually come back down, because co2 can enter the bubble more quickly than air can leave the bubble. It’s odd then, because the molecules can move in and out of the bubble easily. Now I should look up what causes bubbles to sporadically pop. lol
