COEUR d’ALENE — A low, soothing sound flowed from Squid Samson's didgeridoo as he slowly made his rounds in the human chain that encircled him.

Hands were clasped and some eyes were dreamily closed as Samson directed the instrument toward each individual in the ring of people that stood on the lawn of the Coeur d'Alene Public Library on Saturday.

"As the tube gets bigger at the end, there’s more sound vibrations clashing with each other, so it creates a lot more frequencies within the didgeridoo," Samson explained. "Different vibrations can open up certain kinds of pathways in your body. They resonate with different frequencies that your body naturally puts off, like your heartbeat, it's a frequency. When you align the sound with that, it helps your body relax and unwind and you feel a little bit less stress."

Whether they were deepening their spiritual connection with Mother Earth or being fascinated by her many wonders, all who went to the Earth Day Fair had many fun activities from which to choose.

"I love that it’s a wonderful, free community event, but it’s really focused around kids," said Sharon Bosley, outreach and development director for Kootenai Environmental Alliance. "I love that all our educational vendors bring information and crafts for kids to help them understand what they can do to make a difference and help our earth on Earth Day."

This was about the 15th year for the Earth Day Fair, which was organized by KEA and sponsored by the City of Coeur d'Alene in conjunction with several partners.

The fair featured roughly 25 exhibits, vendors and educational booths where fair-goers could make peanut butter and birdseed birdfeeders, score packets of free seeds, learn about hydrology, enjoy a traveling sauna, commit to picking up litter and much more.

The day also included a yoga flash mob, storytelling by the Coeur d'Alene Tribe, a birds of prey demonstration and other activities.

Marie Pengilly, outreach coordinator for the University of Idaho-Coeur d’Alene Community Water Resource Center, enjoyed wowing kiddos with an augmented reality sandbox.

“How it works is you have real sand, but it’s augmented, or supplemented, by the technology. We have an Xbox Kinect that’s scanning the height of the sand and it scans just constantly and then it goes into our computer and it’s projected onto the sand," she said. "It educates kids about water resources and where water moves and how landforms are created. We take it into classrooms and teach kids and we also do community events like this."

Mom Wendy Arbic and daughter Elisabeth, 18, of Coeur d'Alene, participated in the yoga flash mob under the sunny blue skies.

"Every day is a day that we can take care of the natural resources that we have,” Wendy said. "If there’s a day that we can set aside to teach others to also do so, then that’s wonderful. We pass it along to the younger generation.”

Elisabeth said she really enjoyed “seeing everybody celebrate the beautiful resources that we have here.”

The theme this year was "Environmental and Climate Literacy," a national theme that Bosley said came at a pertinent time for the country. She said it's important for people to understand that accurate information about environmental issues is out there, even if people have to look harder to find it these days.

"We need to continue the good work that’s been going on and keep making a difference," she said. "If we can’t do it through our federal government, we can do it locally. The city just recently implemented glass recycling, which is awesome. There are just a lot of other things that are going on in our community that we want people to know they can be involved in.

"We want to get more things implemented and this is the time to do it," Bosley continued. "Just because they’re backing off on talking about it doesn’t mean that we need to. We can still fight the fight and make a difference."
