The key of this lesson was to protect our raw egg from cracking as a group. My idea was to cut the straws and form the air compression wall and cushion with thick layers of tissue paper, then put the protected egg into paper cup and sealed it with scotch tapes. The result was fantastic, as our egg remained unscathed. Reflecting, I realize that we should not overlook ordinary materials as when they are capable of doing much more when they are used in a proper manner.
