Balloon sculptor Rick Wormeli entranced his young audience, including Herndon residents Sydney Schneider, 9, Tabitha Erazo, 5, Amelia Luongo, 7. The multi-colored octopus was a big favorite. Wormeli, an educational consultant, learned the art for his daughter's birthday party. He enjoyed it so much, that many years later, he still volunteers at events like the Floris Chocolate Festival.
