天气玻璃晴雨表
if you are constructing one of these during a spell of bad weather,you will have to wait until the weather improves to see how the barometer acts.如果你正在构建天气坏的法术这期间，你将不得不等到天气好转，看看晴雨表行为。rising atmospheric pressure as a high moves in will press with more force on the surface of the water and push the column of water in the bottle to a higher level.大气上升运动作为一个高压力会继续进行更多的力量在水面的矿泉水瓶，推动中列到一个更高的水平。
materials:材料：
clear glass jar (approx. 18 ounces)透明的玻璃容器内，（约18盎司）
clear, straight-neck glass bottle (approx. 12 ounces)清除，直颈玻璃瓶（约12盎司）
food coloring (blue is nice)食用色素（蓝色是尼斯）
rubber band橡皮筋
step 1:第1步：
find a bottle with a straight neckand a jar that is tall enough for the bottle to sit in upside down without having the neck touch the jar's bottom. also, the bottle must not fit so tightly as to form an air-tight seal.发现密封一直颈瓶和一个罐子是身高不够的瓶中倒坐而无需触摸颈部jar的底部。此外，瓶子必须不适合那么紧，形成一个空气。one combination that has been suggested is a star brand white vinegar bottle and an 18-oz.一个组合，已建议的是一个明星品牌白醋瓶和18盎司。peanut butter jar.花生酱罐子。remove all labels, clean the bottle and jar, and invert the bottle into the jar.删除所有的标签，干净瓶子，罐子，瓶子罐子反转成。
step 2:第2步：
fill the jar with enough waterto come up just over the mouth of the bottle by an inch or a little more.将水倒入罐要拿出足够的刚刚超过一英寸的瓶子口的或更多一点。add a few drops of food coloring.添加几滴食用色素。tip the bottle and jar enough to let a little air escape from the bottle so that the liquid is now up in the neck of the bottle and level with the water in the jar.提示瓶和罐子，足以让一个小瓶子从空中逃脱这样，液体罐在目前的脖子，并在瓶中的水位。
step 3:第3步：
slide the rubber band onto the outside of the jarand position it at the same level as the water.滑动的水橡皮筋缠到同一水平之外的罐子在摆正。set the barometer in a spot out of direct sunlight, where it can be observed but won't get knocked over.设置了一个晴雨表当场被击倒在了阳光直射，在那里可以观测到，但不会。as the water rises and falls in the neck of the bottle, use the rubber band to mark the new level.由于水上升和下降的瓶子的颈部，用橡皮筋，庆祝新的水平。
a demonstration:一个示范：
to show other people how the barometer works,there is this demonstration; find a pot or dishpan in your kitchen and fill it with water.要告诉别人作品的晴雨表，有这样的示范;找到一个罐或厨房迪什潘在你和它与灌水。ask those interested to press down on the surface of the water with their hands, to see how the level of the water rises and then falls when they press down or let up.问到有兴趣的手按压其表面的水，看看如何在水平提高的水，然后按下时跌倒或松懈。explain that the air around them presses against everything and likewise presses down on the water in the jar, forcing the water up the neck of the bottle when atmospheric air pressure rises.解释说，他们周围空气罐压反对一切，同样按下在水面上，迫使空气压力上升了水的瓶子颈部当大气。below is a simple diagram of the basic forces involved.下面是一个简单的力量参与的基本图。
