Things to Do with Science Thursday! Fog in a Bottle

I always try to find some kind of neat thing or idea that you can easily do with your kids on Thursdays. I found this ideas on What their faces light up when they discover the amazing trick you have done :)

Fog in a bottle

Creating fog in a bottle, as in the photo at the top of this page, is a simpler matter. A large jar or wide mouthed bottle is filled with hot water. All of the hot water is poured out except for an inch (25mm) or so at the bottom. A strainer is set over the mouth of the jar, and ice cubes are placed in the strainer. Before too long the cold air from the ice cubes will cause the water to condense from the warm, moist air in the bottle, forming fog.
