ITHACA, N.Y. -- The Ithaca Science Center welcomed its one millionth visitor on Monday!

Alice Hu was the lucky visitor, followed by her twin sister Bella. They both won free lifetime memberships to the Science Center. They also got five minutes to fill a large toy car with as many items from the Science Center gift store as they could.

"It's an exciting time for an organization like ours. We're a fairly small science center in the world of Science Centers, but to have one million visitors is a very exciting time for us," said Charlie Trautmann, the Science Center executive director.

The Science Center has been open for 25 years. There have now been more than one million visitors at its current location of First Street, which opened in 1993.
