I was experimenting with dropping steel balls into water. Some of them coated with hydrophobic stuff, including soot and nose oil. No, that's not a fancy brand name, it just what it sounds like. But after the fun of balls hitting water, I thought it would be interesting to drop a candle into water. I was hoping that the cavity formed by the hydrophobic material hitting the water would allow for the flame to continue burning when the candle went below the surface of the water. I managed to get it just about perfect on the first try.
Not a bad end to the day.
