1
00:00:07,866 --> 00:00:08,483
你看这个

2
00:00:09,099 --> 00:00:10,316
你知道阿基米德吗

3
00:00:10,599 --> 00:00:12,400
是他最早揭示了杠杆原理

4
00:00:12,683 --> 00:00:13,816
我们现在只要把这个

5
00:00:13,866 --> 00:00:15,800
从这个链子中间插进去

6
00:00:16,033 --> 00:00:17,583
然后我们两个这样轻轻

7
00:00:18,483 --> 00:00:19,483
你帮我一下

8
00:00:20,399 --> 00:00:20,899
对

9
00:00:21,316 --> 00:00:23,533
我只需要轻轻轻

10
00:00:25,266 --> 00:00:25,816
开了开了

11
00:00:26,983 --> 00:00:27,733
你没事吧

12
00:00:28,933 --> 00:00:30,766
大哥 都破了

13
00:00:30,866 --> 00:00:31,816
不好意思不好意思
