Wax
- Wax is made of carbon and hydrogen atoms bonded together in long chains.
- The chains are tangled, intertwined, and packed together to make the wax.

Water
- Water molecules are packed more closely together than the long molecules that make up wax.
- The oxygen atoms in water are also smaller and heavier than the carbon atoms in wax. This contributes to making water more dense than wax.

Clay
- Clay contains oxygen atoms like water but also contains heavier atoms such as silicon and aluminum.
- These atoms are packed pretty close together which makes clay more dense than water.
