It makes no sense! You drop an apple in water you’d expect it to sink with how heavy it is… but nope. Floats to the top. Here is why.
Apples are made up of 25% air. Sure there is skin, seeds, and juices too, but there is enough air to make it float. If something is more dense than water it will sink, it is less dense it will float. Apples are less dense than water, so they float! Pumpkins they same thing. Very heavy, but still float because of all the air.
