I tried to create a smoke effect from kettle, hot coffee etc. I tried dry ice. It didn't work too well. I noticed that the the smoke is heavier than air, so instead of going up, the smoke is going down or sideways. What is the best method to create a natural looking smoke/steam? Question #2: What is the best method to create sweat on bottles so they will look as they just came out from the fridge?

Thanks for your tips.
