Banish winter by chucking a snowball into the Ohio

What Folks who remembered to save a snowball from this winter can toss the icy relic into the river using a snowball slingshot. Other solstice-themed activities include two live science demonstrations to help beat the heat, snowflake make-and-takes, an ice moon activity in the Buhl Planetarium and snow cones available for purchase. All-ages welcome.
