00:00:00,000 --> 00:00:02,600
I want to talk about fluorite.

2
00:00:02,600 --> 00:00:06,200
Our names are Daniela, Jaime, Gideon.

3
00:00:06,200 --> 00:00:09,200
Fluorite, fluorite is really interesting.

4
00:00:09,200 --> 00:00:14,600
When you find it in a rock, all the little crystals

5
00:00:14,600 --> 00:00:17,800
will usually be in shape of cubes.

6
00:00:17,800 --> 00:00:23,500
This way, this is the way that minerals naturally grow.

7
00:00:23,500 --> 00:00:27,800
Fluorite is a soft mineral, which

8
00:00:27,800 --> 00:00:31,600
can be scratched with our common name.

9
00:00:31,600 --> 00:00:40,600
Fluorite can be found in many different colors, like this.

10
00:00:40,600 --> 00:00:42,600
It's green.

11
00:00:42,600 --> 00:00:47,600
Fluorite is used in toothpaste.

12
00:00:47,600 --> 00:00:50,600
It's one of the main elements of fluorite.

13
00:00:50,600 --> 00:00:53,600
It's one of the main elements of fluorite.

14
00:00:54,400 --> 00:01:03,400
They help prevent, and sometimes reverse,

15
00:01:03,400 --> 00:01:11,400
the early stage of tooth scratch.

16
00:01:14,400 --> 00:01:16,400
Drink drinking water.

17
00:01:16,400 --> 00:01:22,400
Drinking water, fluorite is isotope in drinking water.

18
00:01:23,200 --> 00:01:28,200
Don't worry, it is good for the teeth.

19
00:01:28,200 --> 00:01:34,200
And don't hurt your small teeth.

20
00:01:38,200 --> 00:01:46,200
But the fluorite thing about it, it is fluorescent.

21
00:01:46,200 --> 00:01:49,200
And what does it mean?

22
00:01:50,000 --> 00:01:58,000
It means if you have a red light or a black light,

23
00:01:58,000 --> 00:02:09,000
the light that can be in those dark minicubes

24
00:02:09,800 --> 00:02:19,800
and move it from two different places.

25
00:02:19,800 --> 00:02:34,800
It might glow in two different colors under the light, like this.

26
00:02:39,800 --> 00:02:41,800
Thank you for your attention.

27
00:02:41,800 --> 00:02:43,800
Any questions?
