Why do some objects float while others sink? I believe that was the same question that brought you here. After my research, I found answers that satisfied my curiosity. On this page, I will show you the list of things that float in water. But first, let us answer the question why?
All sorts of things can float in water regardless of their shape or solidity. Whether an object is flat or pointy, hollow, or solid does not affect its ability to float in water. What determines things that float in water?. Science-pack clarifies that objects are made up of very tiny molecules. Molecules can be packed in close together like in a rock or more spread out like in bubble wrap. The positioning of molecules affects the density of an object.
Objects with tightly packed molecules are denser than those where the molecules are spread out.
Now, according to this website, An object floats when the weight force on the object is balanced by the upward push of the water on the object. The upwards push of the water increases with the volume of the object that is underwater; it is not affected by the depth of the water or the amount of water.
If the weight force down is larger than the upward push of the water on the object then the object will sink. If the reverse is true then the object will rise – rising is the opposite of sinking.
Different objects float at different levels in the water because as most regular objects are lowered into the surface of the water, the upward push of the water steadily increases until it is in balance with the weight force of the object, and the object then continues floating at this level with the two forces in balance.
Many objects that are hollow (and so generally contain air) float because the hollow sections increase the volume of the object (and so the upwards push) for very little increase in weight force down. However, it is not necessary for an object to contain air in order to float. No object can float without some part of it being below the surface of the water.
Things that float in water
- Apples
- Balloons
- Bananas
- Cork

- Empty Bottles.
- Feather
- Leaf
- Lemons
- Natural Rubber
- Oil
- Oranges
- Pears

In conclusion, we should view floating as being a result of the balance of the weight force on an object and the upward push of the water on the submerged part of the object.
