The free 2011 Kirkland Summer Concerts kick off with a performance by educator and juggling master Rhys Thomas at 10 a.m. Tuesday, July 5 at Marina Park in Kirkland.

His Science Circus explores gravity with bowling ball juggling, gyroscopics with Chinese yoyo spinning, balance with six foot unicycle riding, centripetal force with cowboy lariat swinging, and demonstrates inertia by twirling nine glass bowls while pulling a tablecloth from under a place setting. Get ready to enjoy 55 minutes of hilarity, dexterity and physics.

Don’t miss the grand opening of the evening shows from 7-9 p.m. Thursday, July 7 with Ruby Dee and the Snakehandlers, bringing rockabilly, roots, and country all the way from Austin, Texas!

The Kirkland Summer Concerts are organized by volunteers and paid for by local businesses and individual donors. For more information and the schedule, go to KirklandSummerConcerts.org.
