Explanation:

Buoyancy force is more than gravity for materials with density smaller than water which holds for plastic and hence it comes up to the surface of water.

The buoyant force acting on the block of plastic is more than its weight. As a result of this, it comes up when released under water. The cause of this larger buoyant force on the block of plastic is due to its density being smaller than that of water.
