Fill a container up with warm water. I use warm water. The reason for this is. Eggs are porous. If you put an egg in cold water， it will contract and draw any bacteria that is on the outside of the shell in through the pores. This is not good. So， if you use warm water， the egg will expand， and you will notice that little air bubbles form on the shell.
用溫水注入容器。我就是用溫水。其原因是，雞蛋是多孔的。如果你把一個雞蛋放在冷水中會收縮，並且透過蛋殼外側的毛孔吸收細菌，這是不好的。因此，如果使用溫水，雞蛋會脹大，你會發現在蛋殼上有小氣泡形成。
Put your eggs into the warm water， and look at them.
A very fresh egg will sink to the bottom and lay on it's side.
Week old eggs will rest on the bottom but the fat end of the egg will rise up slightly.
Three week old eggs will be balanced on pointy end with the fat end sticking up.
Old eggs will be floating， bobbing along the surface of the water.
These floaters should be tossed as they aren't any good to eat.
把雞蛋放入溫水中，並觀察它們。
1) 一顆很新鮮的蛋，會沉入水底躺平。
2) 一週的蛋會停留在底部，但是較胖的一端會小幅升起。
3) 三週的蛋會豎立起來，較胖的一端朝上成平衡狀態。
4) 放久了的壞蛋會浮起來，沿著水的表面上下浮動。
這些漂浮的蛋應該扔掉，因為它們不宜再食用。
