'Pressure' Walking On Eggs!

What do you need?
To try this, all you need to prepare are several large cartons of eggs.

What to do?
Place cartons of eggs on the floor. Then carefully walk on them. What do you think will happen to the eggs? Will they break?

Watch this video! 

What happens?
This activity proves that 'pressure' is 'force' acting on one unit of surface area. As surface area increases, pressure decreases if the force is kept constant. As you walk on the eggs, they will not break as the surface area of the sole is bigger compared to if you apply force with an object that has a smaller surface area,  such as pressing on an egg with a nail.
