The "aha moment"(顿悟时刻) for Arjun Nagendran came one recent afternoon while he was cleaning up the muddy paw prints, and his pet dog, Rocky, was tracking across the house "again".
"Why not make shoes for dogs?" the 10-year-old boy thought.For most kids, the moment might have
ended right here.But for Arjun and five of his classmates from Littleton School, an accidental idea proved
talent when they won first place at the first-ever Student Inventors Day at the Liberty Science Center in
Jersey City. The winning invention, "Green Paws"-an eco-friendly dog shoe made from bark, three leaves and recycled rubber-got the group a $1,000 prize, two television appearances and a shot at being the
next "As Seen on TV" hit product.
More than 20 schools, most of them from New Jersey, gathered at the center to show their green
inventions. Each team had 10 minutes to introduce their inventions to the judges. In the end, the chief
judge Khubani announced that it was the Green Paws product that stood out, particularly because his
company had been looking into the very idea of how to keep paws clean.
Pet products are usually popular sellers, he said, noting that his company has marked four new pet
inventions this year alone. And while his senior managers had put forward the idea of new paw wipes,
they had never thought of pet shoes, he said.
"We thought about cleaning pets' paws, but we never thought about keeping them clean in the first
place." Khubani said after the event. "They actually have an idea that is marketable." The company will
begin conducting market research on Green Paws this week, he said. But Arjun and his team will have to
put off another day before they receive congratulations from their classmates.
