Neither bottles nor cans will actually explode because the difference between the cabin and sea level air pressure isn't that much and the containers are already able to handle some. When you'd open a plastic bottle you'd get a bit of a pop. And if you drank most of the bottle and resealed it, it'd crumple when you returned to sea level.

The effect only applies to gas since it's compressible under pressure. Liquid isn't, so it doesn't matter what the outside pressure is. So the cans (and full bottles) might have a little pop from the gas at the top and it might be a little fizzier at altitude, but most of the volume is liquid so it's not that much.
