As these children play “toss” with the balloon the LED inside the balloon constantly blinks. The heart of this balloon is an LED bulb which is attached to a button cell and a blinking circuit. The black tag is like an ON /OFF switch. Once the black tag is pulled out the LED inside the balloon keeps blinking. If you push the tag back the LED stops blinking. Place this LED with the blinking circuit inside the balloon. Blow up the balloon with air and tie its mouth. Well as the children play with the inflated balloon the balloon will keep blinking to their delight.
