No, it's the air volume on each item. For example, a balloon filled with air will surely float on the water, but a ballon filled with water will not float. That's because there is no air in the second one and that makes it even heavier.
The force that makes objects float in a fluid, such as water, is called buoyancy. It occurs when the weight of the displaced fluid is equal to the weight of the object, allowing it to stay afloat.
Things sink or float in oil based on their density. Objects that are less dense than the oil will float, while objects that are denser will sink. This is due to Archimedes' principle - an object will float if the weight of the fluid it displaces is equal to or greater than its own weight.
The force that helps things float is called buoyancy. It is the upward force exerted by a fluid, such as water or air, that opposes the weight of an object immersed in the fluid. Objects float when the buoyant force is greater than or equal to the weight of the object.
The force that causes objects to float on water is buoyancy. Buoyancy is the upward force exerted by a fluid (in this case, water) that opposes the weight of an object placed in the fluid. If the buoyant force is greater than the weight of the object, the object will float.
Buoyant force makes a straw and clay ball float. When an object is placed in a fluid, such as water, the fluid exerts an upward force on the object that is equal to the weight of the fluid displaced by the object, causing it to float.

It is quite common for various things to float in water. But any liquid can cause things to float.
because the weight of gravity on the bottom of the candle makes its self float
Because it is full of dissolved salt which makes the density of things lighter, and therefore makes them float.
Because there is less density.
well when the salt dissolves into the water it makes water considerably denser and there for the water can hold more weight by:Matthew Shouse

Often the element helium (atomic symbol: He) often makes objects float, most commonly balloons.
Salt Water, because it is makes things more buoyant.
helium is a light mass of weight in which will float unlike a hevy object that will fall to the ground
