It’s an experiment. If the ice sheet melts in entirety nothing will happen. When the earth was formed, some water remained liquid and some froze. It’s the same amount of water in either case. The oceans will not rise, the glass will not overflow.

The amount of water is the same but during ice ages the sea level decreases as more ice is located on land. That’s what causes land bridges to form between continents.
Same thing here...if you free up (in theory) all the fresh water locked up in ice at the north and south poles...melt it...the sea level will rise. Will that happen? No way...but what you are saying about NOTHING happening is false.
Here's an experiment. Get a 20 gallon aquarium. Fill it with small gravel so that they are at a 45 degree angle up the side of the tank. Fill it 1/2 with water. Mark the level of water. Now...on the "dry side" of the tank...put a bunch of ice on top of the gravel. Let the ice melt.
Did the water in the tank rise? You bet.
Same thing would happen with the earth.
