In the pool of liquid wax below a lighted candle wick carbon fragments
shoot out vety fast on the surface. They sink and travel back slowly, thay
circulate slowly upward near the wick and shoot out quickly again.
Intuition suggests that the particles should rise fastest near the heat
source where convection should be maximal. Not so in practice.
