Orange peel experiment

We wrote predictions of which orange would float. Unpeeled or peeled.

I predict that the unpeeled one will float because it is waterproof and the skin makes it float. Sam C

I predict that the one without the skin would float because it is the lightest. Max

I predict the one that is peeled because it is airtight. Mica

The peeled one sank. The un peeled floated because the skin acts as a life jacket to make it float. We also tried just orange peel and it floated.
