AI Thread Summary
The discussion centers on an observation made when holding a glass of cold water over a candle flame, noting that the flame bent away from the glass before contact. The poster speculates on the cause, proposing three possible explanations: cold air descending from the glass may have disrupted the hot air currents, the glass could have blocked the hot air, causing it to spread out and divert, or a combination of both effects. The poster invites others to conduct experiments to explore the phenomenon but expresses concern about potential disapproval from their mother regarding such experiments.

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?

Why don't you do an experiment or two and determine the cause?
 
Because my mom will get angry.
 
Just ONCE, I wanted to see a post titled Status Update that was not a blatant, annoying spam post by a new member. So here it is. Today was a good day here in Northern Wisconsin. Fall colors are here, no mosquitos, no deer flies, and mild temperature, so my morning run was unusually nice. Only two meetings today, and both went well. The deer that was road killed just down the road two weeks ago is now fully decomposed, so no more smell. Somebody has a spike buck skull for their...
