More than 200 children helped christen a new water park at the Evergreen Aviation and Space Museum in McMinnville.

At Wings and Waves, kids can climb out of an actual Boeing 747 jetliner to slide down a 62-foot water slide. The News-Register says eight winners of a school water science essay and drawing contest — and their classmates — were special guests Monday during the first hour the water park was open. The public opening came at 11 a.m.

Evergreen Founder and Chairman Del Smith and museum Director Larry Wood urged the students to have fun on the water park slides and in the children’s museum upstairs.

That museum features hands-on exhibits about space exploration and the water cycle.

The aviation museum opened 10 years ago and the space museum opened three years ago.
