A toy wooden canoe is floating in a swimming pool.
Which will raise the level of the water in the pool higher:
Dropping a penny into the pool or, dropping the penny into the canoe?
Objects floating in liquid displace a volume of liquid equal to the object's weight. Sunken objects displace an amount of liquid equal to the object's volume. Since pennies sink, they are more dense than water. Therefore adding the penny to the boat (i.e. floating) will displace more liquid.
