Only if they are so old you won't even want to think about eating them.
No, a coin can not float on gasoline.
The fats (i.e. cream) from the milk will dissolve in the gasoline and the the resulting gasoline/cream solution will float on the water from the milk.
Gasoline
No, a piece of platinum will not float on gasoline. Platinum is a dense metal with a high specific gravity, which means it will sink in liquids that are less dense than itself, such as gasoline. Since platinum is significantly denser than gasoline, it will submerge rather than float.
The hydrometer will float higher in glycerin than in gasoline because glycerin is denser than gasoline. The level to which the hydrometer floats indicates the density of the liquid it is submerged in.
No, a coin can not float on gasoline.
Yes, wood will typically float in gasoline because the density of wood is lower than that of gasoline. This means that the wood will be less dense than the gasoline and will float on its surface.
yes it does float because it has less density. Therefore it will float.

Eggs float when they are older because air enters the eggshell as it ages, creating a larger air cell inside. This means the egg is less fresh.
Glycerin
Gasoline is less dense than water, so it will float on top of the water rather than sinking. The difference in density between the two liquids causes the gasoline to create a distinct layer on top of the water.
