Rocks and Minerals
Did you know that some rocks can float in water? Or that some minerals glow under UV light? Bart Kotarba of the Northwoods Wildlife Center in Minocqua will show you this and more in a very hands on presentation.
This program is sponsored by the Friends of the Mercer Library as part of our 2018 summer kids programs, and all are welcome. For more information, call the Mercer Library at 715-476-2366.
