Interesting experiment

Today, my favorite composition class has arrived. It is said that the teacher is going to take us to do an interesting experiment today.

The teacher brought a mystery to the classroom, took out a few fat seas from the bag, and took out a transparent glass. Give the sea to each of us for one to let us observe.

I look at this tasteless fat sea, wearing a brown coat, pointed on both sides, bulging in the middle, like a deflated rugby. Also covered with fine lines, like the wrinkles of the old grandmother.

This is, the teacher put the fat sea into the cup and pour it into the cup with boiling water. This deflated rugby immediately surfaced, becoming more and more fat as time passed by. Getting fatter, who is getting yellower and more turbid. The fat sea gradually changed from a pointed, bulging "small point" in the middle to a "big guy" like a white fungus.

This experiment allowed us to learn a little medical knowledge and let us witness the miracle.
