As you may know, pumpkins are supposed to float due to their hollow middle. So what happened with our pumpkin? We took a closer look and attempted the experiment again with a smaller pumpkin (ours was medium sized), which did float (they are supposed to regardless of size due to it being hollow). So why did ours sink? According to our research, if there are any holes in a pumpkin (we have used them in other activities prior to this experiment, so it is possible), water is able to get into the hollow cavity, which would flood it causing it to sink. Pumpkins are less dense than the water. An object floats if its mass is less than the mass of the water it displaces when it is placed on the surface.
