In Disney Adventures Unlimited Donald Ducks nephews Huey Dewy and Louie fill a sunken ship with ping pong balls to bring it up to the surface, true (Possible) or false (impossible) ?

This is theoretically possible because ping pong balls are filled with air and are much less dense than water. By filling a sunken ship with enough ping pong balls, you increase the overall buoyancy of the ship, allowing it to rise to the surface. This principle is similar to how submarines use ballast tanks to control their depth, and demonstrates Archimedes' principle of buoyancy.
