blowing air gives more oxygen so it makes the fire bigger
Fire needs three things: fuel, heat and oxygen (also known as the fire triangle). By fanning the fire, you are increasing the amount of oxygen, so it can burn more fuel and so be hotter. Incidentally, taking away any of those three things will extinguish the fire.
Dakota Fanning's role in New Moon is very small as her character Jane only appears in the later part of the movie/book. In Eclipse and Breaking Dawn, Fanning's role will be much longer.
catastrophizing
In the fall. Female makes a gravel "redd" by fanning on gravel to remove sediment and making a small indent in river bottom. Female lies on redd and then releases eggs. Males are eagerly waiting behind the female to fertilize! Whoo Hoo!
To make a big deal out of something small
No. An acid with a large Ka is stronger. A lower pKa indicates a stronger acid.
Cats would be much much stronger if we would be as small as them
no
Steel is a mixture of iron with a small amount (typically less than 2%) of carbon. Increasing the amount of carbon makes high-carbon steel, which is harder and stronger, but more brittle.
Unless you are talking about a metal bb gun, no. All bbs are standard unless metal. And yes, big bbs are stronger than small. Learn physics.
Fire Traps are usually escaped by blowing into the little microphone set into the DS, usually just a small rectangle hole with the letters "MIC." next to it. It registers at the sound and makes it disappear. If you can't find it, try blowing at different points on your DS or simply yelling at the DS. Although it sounds stupid in writing its how it works.
