Education English | Procedure Text : The Brine Effect | You will need : table salt, a large glass, an egg, a teaspoon, a dessert spoon and water.
How to do it:
1. We half fill the glass with water. Then, using the dessert spoon, we carefully put the egg in water. The egg sinks to the bottom
2.Now we add 10 tablespoons of salt in water and mix thoroughly to make brine.
3. We put the egg in the water again. The egg floats. We take the egg out and slowly fill the glass totally.
5. We put in the egg again.
The egg remains suspended in the centre of the glass.
Do you know why? In the first stage, the egg was denser than clear water, so it sank. In the second stage, salt water (brine) was denser than clear water, helping the egg to float. Finally, when clear water was added, it floated on the brine, making the egg sty in the middle, as it has more density than clear water, but less than the brine.
