As soon as the teacher announced that the holiday was over, I pushed the bench under the table and rushed out of the classroom without looking back, regardless of calling my little friend behind me.
Out of the teaching building, I am happy to jump three feet high, I wish to let the whole world feel my joy.
On the first day of the holiday, I had a good sleep in. When I woke up, I opened my eyes and looked around. A ray of sunshine had already poured into my bedroom and my family had gone to work.
I hummed a tune, slowly leisurely got out of bed, went to the kitchen to find something to eat. Eating and Thinking: this does not need to read early, there is no teacher's reprimand and supervision of the comfortable days can be really comfortable.
Suddenly, an idea flashed into my mind: since I am alone at home and nobody interferes, why not do some interesting little scientific experiments?
Do what you say. I found a science book about interesting experiments from my desk. Turn a page, is an experiment about the rise and fall of eggs.
I was excited to read the content carefully, according to the above said, the first to a basin of water, will be a boiled egg thrown in, the egg immediately sank to the bottom of the water. I began to add a few spoonfuls of salt and kept stirring, and the egg slowly left the bottom and floated in the middle of the water. I beat while the iron was hot, and added half a bottle of salt. After stirring repeatedly, the water became more and more muddy, and the eggs soon surfaced, and the shell began to crack.
I was surprised and pleased. Then, a second experiment was carried out. Place the skinned egg on a glass bottle with a smaller opening than the egg.
At first, I tried to press the egg into the bottle, but it didn't work. No matter how hard I try, the eggs just don't go down, as if they are two magnets with the same magnetic poles, repelling each other. Then, I took a lighter according to the method in the book, kept fuming the bottom of the bottle, and the egg was magically retracted into the bottle. I was stunned. This is really incredible!
But how can the eggs come out? I tried to put the bottle's mouth down and cautiously burned it with a lighter for a while, but the egg gradually shrinked out.
During the whole summer vacation, I was immersed in the joy of scientific experiments. I have done dozens of experiments, and really appreciate the wonderful place of nature.
This is really a fun summer vacation!
