Mercury
When liquid mercury is placed on wax paper, the mercury will not be absorbed or react with the wax paper due to the non-polar nature of wax. Instead, the liquid mercury will form droplets and bead up on the surface of the wax paper due to its high surface tension.
WHEN IT MELTS...It melts! It goes all soggy and droopy and liquid-ish and then disappears...To a secret place...Nobody knows where...Or do we? xD :L
Yes, a lava lamp works on the principle of density. The lava lamp has two liquids of different densities (wax and water) that are heated by a light source at the base. As the wax heats up and becomes less dense than the water, it rises towards the top of the lamp. When the wax cools down and becomes denser, it sinks back down.
No, methane is not found in wax. Wax is primarily composed of long-chain hydrocarbons, such as paraffin and microcrystalline wax. Methane is a simple hydrocarbon gas composed of one carbon atom bonded to four hydrogen atoms.
For beeswax, density ranges from 0.958 to 0.970 grams per cubic centimeter (g/cc). Parafin is about 0.93 g/cc. Carnauba wax runs about 0.97 g/cc. Aside from a number of synthetic waxes, there are several animal and vegetable waxes as well as several mineral and petroleum waxes. They are pretty much all a little less dense than water. Wikipedia has a brief article on wax, and a link is provided.

The density of candle wax can vary depending on the type and composition of the wax, but it typically ranges from about 0.8 to 1.0 grams per cubic centimeter. The density of the wax will also change depending on its temperature, as wax expands when heated and contracts when cooled.
The volume of a substance like wax is dependent on its density. Without knowing the density of the wax, it is not possible to calculate the volume from the mass alone.
Paraffin wax has a density of roughly 0.8 gm/cm3 . It will float in any fluid whose density is greater than roughly 0.8 gm/cm3.
The density of wax is less than water because wax is less dense than water. In other words, the mass of wax for a given volume is less than the mass of water for the same volume. This is why wax tends to float on water.
The density of parafin wax is about 0.93 g/ml - less dense than water. Liquid wax is less dense than that, but I am now sure of the value.
As in most substances, solid wax is more dense than liquid wax. Density, by definition, is mass divided by volume. If the volume is smaller, meaning less space occupied, than the density increases. In a solid, the temperature lowers, the molecules have less energy and are less active. Therefore, they take up less space, equalling a smaller volume. Small volume, more density.

depends on the type of wax. Beeswax candels should float because their density is slightly less than that of water.
The wax substance is more dense than the liquid when cool and less dense than the liquid when heated. The wax moves by density convection.
Sealing wax typically sinks when placed in water due to its density being higher than that of water. However, this can depend on the specific composition of the sealing wax.
