Build water slides at library

Teens will build waterslides for marbles Monday, June 18 in a free activity at the Aspen Drive Library, 701 Aspen Drive, Vernon Hills. Participants create epic waterslides filled with loops, twists and turns. The catch? The marble passengers need to ride safely from start to finish. The program will run from 2:30 to 4 p.m. To register, call (847) 362-2330, visit webres.cooklib.org, or go to the library.
