I'm not sure if this goes here, but there isn't a "General Science" section. Today I got a glass of really cold water, and noticed a candle on the table. I felt like collecting some carbon on the bottom and held the glass over the flame. The flame bent away from the bottom of the glass before it had touched it. I wonder what caused this. I think it was either: 1. Cold air fell from the bottom of the glass and pushed the hot air currents down 2. The hot air were stopped by the glass, and as they spread out pulled the overall current down the path of least resistance to the side. 3. A little of both. What do you think?
