00:00:00,000 --> 00:00:02,000
Hello! Our names are

2
00:00:02,000 --> 00:00:03,000
Ibrahim

3
00:00:03,000 --> 00:00:04,000
Juan

4
00:00:04,000 --> 00:00:05,000
and Sergio

5
00:00:05,000 --> 00:00:07,000
Our machine is a balance

6
00:00:07,000 --> 00:00:10,000
that can help you

7
00:00:10,000 --> 00:00:12,000
with objects

8
00:00:12,000 --> 00:00:14,000
way smaller

9
00:00:14,000 --> 00:00:16,000
We use it

10
00:00:16,000 --> 00:00:18,000
to cook cups

11
00:00:18,000 --> 00:00:19,000
sticks

12
00:00:19,000 --> 00:00:20,000
rubber mats

13
00:00:20,000 --> 00:00:22,000
sand

14
00:00:22,000 --> 00:00:24,000
and tape

15
00:00:24,000 --> 00:00:27,699
and dirt

16
00:00:27,699 --> 00:00:28,699
First

17
00:00:28,699 --> 00:00:29,699
we do

18
00:00:29,699 --> 00:00:35,700
We put two holes to the bottle and we put steel across it.

19
00:00:35,700 --> 00:00:39,700
Then, we put the caps with rubber mats.

20
00:00:39,700 --> 00:00:45,700
And finally, we put all the sand that has filled the bottle inside the bottle.

21
00:00:45,700 --> 00:00:52,700
Now, we will show you how the balance works.

22
00:00:52,700 --> 00:00:58,780
If you put an object with a lot of mass, it goes down because it's an unbalanced force.

23
00:00:59,899 --> 00:01:07,659
But if you put two objects with the same mass, it's a balanced force.
