Okay, if you didn't have eggs or you didn't have the materials 00:00:00
I will do the experiment for you. So let's see what happens 00:00:05
first the 00:00:10
Egg number one. We are going to put it into fresh water without salt. What happens here? 00:00:12
it sinks 00:00:21
Because of the density the density here of the eggs is higher than the water 00:00:22
so that's why it goes down, okay, to the bottom. When the water has salt, let's see 00:00:30
if the density changes or not, okay? We put the egg number two into here, okay, and 00:00:39
you can see it floats. That means that the salt water has more density than the 00:00:50
egg. And remember the third egg? Yes, half of the water we put it and it floats. But 00:00:58
what happens if we add more water? Okay, we need a little more. You have to pour 00:01:15
it very very slowly and you can see that it floats but it stays in the middle. 00:01:32
Why does it happen? Here's the thing. We had this part of water with salt, that means that the density is higher, it goes down, and we add some more fresh water without salt that stays on the top. 00:01:45
So that's why the egg is in the middle, because the egg has less density than the salt water, but it has more density than the fresh water. 00:02:03
That's why the number three stays. 00:02:15
I hope you understood this. 00:02:17
Okay, ask me any question you have. 00:02:20
Bye-bye. 00:02:22
