A lit cigarette, dropped in a puddle of water, will always travel in the direction of the cherry (Away from the filter) for a couple seconds.
However, I am unsure whether that is related to the heat from the suffocated cherry transferring to the water reduces the density of the water by causing the molecules to move away from each other due to the increase in energy, or if it is simply that the remaining tobacco absorbs water more quickly than the filter end.
Something to think about.
