    DIRECTIONS

    1.  Shake first one bottle and then the other, paying close attention to the resulting sounds.
    2.  Shake each again while observing the quantity of bubbles in the water.
    3.  Note that the air inside bottle A cushions the water from hitting against the inside of the glass; while in bottle B the water with little air above it slaps noisily against the glass sides.
