Meet The Balloonatics

\tIt's crunch time for the 'balloonatics' at Macy's Parade Studio. The balloons themselves, which are designed and fabricated in a warehouse in New Jersey, are getting their final checkup before the Macy's Thanksgiving Day Parade. John Piper and Jim Artle take us around the studio and spill the secrets of inflation, explain how to calculate whether your balloon will float, and explain why the balloons look better after a little time in the sun.
