    摘要: A musical balloon has an electronic music-producing device contained within an inner, nearly opaque balloon. An outer balloon of any desired color and design, more light transmissive than the inner balloon, covers the inner balloon. The electronic music-producing device includes an on/off switch sensitive to light. When the balloons are deflated, the rubber material is dense enough to keep light from activating the music. However, when the balloons are inflated, the rubber material is stretched to a more translucent condition, and sufficient light permeates the balloons to activate the switch and the music.
