Monday marked the first day of summer and the science museum's annual Snowball Day. Visitors are encouraged every year to save a snowball from the winter in their freezer and then take it to the science center on the first day of summer. Those who do get to name their own price to get into the museum for the day.
But the most fun comes when they get to throw their snowballs into the Ohio River from the deck of a submarine that is docked outside the museum.
