Title:
    MODULUS: YOUNG’S, SHEAR & BULK
Description:
    Demonstrates the difference between each type of moduli.
Equipment:
    1. Large sponge
Procedure:
    1. Crush the ends of the sponge straight towards each other to show Young’s modulus.
    2. Push one end of the sponge upward and the opposite end downward to show shear modulus.
    3. Crush the sponge into a ball, pushing from all directions to show bulk modulus.
