Hi, I'm Matthew.

2
00:00:20,980 --> 00:00:26,320
Today on Experiment Time we're going to make a model of our stomach and our intestines,

3
00:00:26,320 --> 00:00:28,739
parts of our digestive system.

4
00:00:28,739 --> 00:00:46,500
So using a strong bag, some biscuits, a banana, a little water, some orange juice, a cup with

5
00:00:46,500 --> 00:00:53,579
a hole in it and a stocking. We're going to show you what happens to food after we've

6
00:00:53,579 --> 00:00:58,859
eaten it. We're going to show you a model of our intestines and stomach. What do you

7
00:00:58,859 --> 00:01:05,680
think happens to food after we've chewed it and swallowed it? Let's find out. So, let's

8
00:01:05,680 --> 00:01:31,930
say this bag is our stomach and this is our food. A little water for our saliva and some

9
00:01:31,930 --> 00:01:44,890
orange juice for our gastric juice. There. So this is our model stomach. Okay, now I'm

10
00:01:44,890 --> 00:01:54,709
going to break it down a bit more like this for about 30 seconds. So, this is the food

11
00:01:54,709 --> 00:02:01,590
in our stomach. After the stomach, where does the food go? That's right, into the small

12
00:02:01,590 --> 00:02:13,020
intestine. Look, I've got one here. It's a stocking. Now, can I have an assistant please?

13
00:02:13,020 --> 00:02:20,840
Can you hold the stocking top open like this? Now I'm going to cut the stomach like this.

14
00:02:20,840 --> 00:02:55,590
Oh wait, let's get a bowl because this will get messy. Now we're going to squeeze the

15
00:02:55,590 --> 00:03:04,039
intestine a little to see how the small intestine works. Look, you can see the nutrients and

16
00:03:04,039 --> 00:03:27,180
the water that our body needs. Okay, so now we're going to cut the knot and the food is

17
00:03:27,180 --> 00:03:44,159
going to go into the large intestine where more water is absorbed. Then the food is going

18
00:03:44,159 --> 00:03:56,509
to expel from our bodies like this. And this is the end of the food's journey. As you've

19
00:03:56,509 --> 00:04:02,930
seen, this has only taken us a few minutes. How long do you think it takes in real life?

20
00:04:02,930 --> 00:04:10,889
six to eight hours. So, that's how our digestive system works. Why not try it for yourselves?

21
00:04:10,889 --> 00:04:11,990
See you later alligator.
