Show answer Hide answer
Answer
The peel traps air, lowering the orange's density.

Explanation

  • The peel is spongy and holds many tiny air pockets.
  • This makes the whole unpeeled orange less dense than water.
  • So the unpeeled orange floats.
  • Without the peel, the orange is denser than water and sinks.
The air-filled peel makes the orange less dense than water, so it floats; peeled, it sinks.
