Save a snowball, name your own price on Summer Solstice at Science Center

 


Snow has arrived in the region again, giving the public another chance to make snowballs – for Carnegie Science Center’s annual “Snowball Day” celebration of the Summer Solstice.

All visitors who make a snowball this winter, save it in their freezer, and bring it in on the first day of summer, Monday, June 20, 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.
