你需要什么?◆一个玻璃杯(杯口大小要刚好让一个鸡蛋卡住掉不下去)◆一个鸡蛋壳◆土壤和一些生长迅速的种子(比如绿豆)◆牙膏开始动手喽!先将湿润的土壤装进蛋壳,并种下几粒种子,再将牙膏涂抹在蛋壳上起保护作用。然后把蛋壳放到装有水的玻璃杯上,蛋壳底部要刚好与水面接触,之后就不要向土壤中加水了。现在,只需要耐心等待,看看有什么神奇的事情发生。 What do you need? ◆ A glass (the size of the cup just keeps an egg stuck) ◆ An egg shell ◆ The soil and some rapidly growing seeds (such as green beans) ◆ Toothpaste to start! Into the eggshell, and planted a few seeds, and then spread the toothpaste in the shell play a protective role. Then place the egg shell on a glass filled with water. The bottom of the shell needs to come into contact with the water surface immediately. Do not add water to the soil afterward. Now, just be patient and see what magical things happen.
