Save a snowball now and name your own price on June 21 Put on some really warm mittens, bundle up, and go out there and make snowballs! It won’t be easy, since this snow is really powdery, but there’s a great payoff. Carnegie Science Center is announcing its annual “Snowball Day” celebration of the Summer Solstice, and now is the time to get ready. All visitors who make a snowball this winter, save it in their freezer, and bring it in on the first day of summer, Sunday, June 21, will be able to choose what they pay for general admission. In addition to naming their own price, visitors will be able to launch their snowballs into the Ohio River (weather permitting). In past years, hundreds of snowballs survived the winter and spring in freezers throughout the region and made their way to the Science Center—in coolers, freezer bags, frosty coffee cans, and plastic storage containers. The Science Center invites visitors of all ages to start stockpiling snowballs now and remember these snowy facts: *Snow forms from tiny crystals in clouds. Snow is not frozen rain; that’s called sleet. *Most snowflakes melt before reaching the ground. *No two snowflakes are identical. *Each snowflake is made up of two to 200 separate crystals, on average. *Although it appears white, snow actually is transparent. Snow crystals act as prisms and break up the Sun’s light into the entire color spectrum. The human eye can’t handle that kind of sensory overload, so it is processed as white. If a region’s soil contains more iron, giving it a reddish tinge, snow may appear pink—wind will blow dirt and dust into the atmosphere and clouds, where the snow crystals form initially.
