00:00:06,830 --> 00:00:23,829
For this experiment, we need a can, a piece of a CD, a piece of a balloon, a plastic tube, an American tape and a laser pointer.

2
00:00:23,829 --> 00:00:27,829
First, with the piece of balloon, we put on the can.

3
00:00:27,829 --> 00:00:35,829
Once we have it, we need also a piece of American tape and the piece of CD.

4
00:00:35,829 --> 00:00:44,829
And then, with the plastic tube and the laser pointer, we need to point to the CD.

5
00:00:44,829 --> 00:00:49,829
And once we have it, we need to fix it with the American tape.

6
00:00:49,829 --> 00:00:59,829
And once we have fixed it, the laser pointer to the plastic tube and the plastic tube to the can, we finished.

7
00:00:59,829 --> 00:01:03,829
So now, we just need a volunteer to prove it.

8
00:01:03,829 --> 00:01:33,909
So, I call my father for that.
