Birthday bash at Mobius

Kids and their families are invited on Saturday to a whirlwind of a birthday party at Mobius Kids, a children’s museum in downtown Spokane.

And here’s the best part: Everyone gets in free.

Plus, you’ll be the first in town to experience a brand new, interactive exhibit, AirPlay.

“It’ll blow you away,” promises the museum’s press release. “Come discover what air can do, where it works, and how much fun playing with air can be.”

Watch winds whittle and reshape sand dunes. See how air makes model boats “sail” across a tabletop. Or send a blast of air through an “air cannon” all the way across the room.

Then, try to float and maneuver foam balls on invisible air streams. And paint a wall of shimmer disks with a spray of air.

Once you’ve got the hang of it, race foam balls through streams of smooth and bumpy air.

Bet parents will learn as many things as their kids do.

Kristi Luntzel, museum education coordinator, said that among the concepts explored are: “How do airplanes and helicopters remain aloft? How do hurricanes and tornadoes create disasters on land, and why are some areas spared? How have the hills of the Palouse region been sculpted over time, and how could the Dust Bowl of the Depression Era take place?

“These are bigger questions that can be explored on a smaller scale through AirPlay,” Luntzel said.
