Question

when the ice melts the water will have no place to go

Answer 1

Ice is less dense than water.

That’s why ice cubes float and why lakes freeze from the top down.

So since water is more dense than water-with-ice-in-it, the overall level of ice-plus-water will go down in the sealed bottle as the ice melts, and if it’s truly airproof, it will create a little suction and resist when you try and open it later.

So, nah, no exploding bottle. Sorry to disappoint fam.
