Chapter 643: Important Things (4)

At Yun University, in the laboratory.

At the end of Mu Huan's experiment, a new problem suddenly arose. In order to not delay the reporting time, she spent almost every day in the laboratory.

While she was waiting for the results of the experiment, she went out and wanted to take a nap. Suddenly, she thought of the thing that her grandfather had left for her. She took it out of her bag and studied it carefully.

However, after looking through it carefully again, she still did not find any mechanisms. She knocked on the body of the boat, weighed it in her hand, and then placed it on the weighing scale. Then, according to the volume and density of the materials, she calculated its weight. Although the weight was not much different from the weight she had calculated, with her meticulous calculations, if there were no problems with the boat, there shouldn't be a difference in its weight.
