Stacked By Science: The Amazing World of Floating and Sinking
Oscar Heyman
This Image depicts the difference in density among household liquids such as
honey, water, and oil portrayed through what objects float or not. Density is how
much matter is packed into a certain amount of space. Honey has the greatest
density making it sink to the bottom of the glass. Water is less dense than honey
but more dense than oil so it floats on top of the honey, but sinks beneath the oil.
The objects that are placed in the cup float or sink depending on their density in
relation to the liquid. For example, the screw at the bottom of the cup is more
dense than all of the liquids making it sink to the bottom. The chocolate coin floats
on top of the honey because it is more dense than olive oil and water, but not
honey. The strawberry floats above the water because it is more dense than the
olive oil but less dense than the water. Finally, the bottle cap is the least dense of
all of the objects, but it also acts as a boat/raft allowing it to float on the very top.
This experiment shows how the change in density in objects and liquid affects their
ability to float or sink in different layered liquids.
