The Children’s Museum of New Hampshire in Dover will be hosting a “Build It, Fly It Day” on Wednesday, July 28, from 10 a.m. to 3 p.m. at the museum.

Young imaginations will soar as children create their own flying machines using a variety of everyday materials in this high-flying challenge. Kids will learn about the principles of aerodynamics and flight as they test their creations in the museum’s two-and-a-half-story “Build It, Fly It” exhibit. Whose invention will fly, flip or flop? Visitors can also try their hand at constructing some other simple flyers to test and take home.

The Children’s Museum of New Hampshire is located at 6 Washington St., Dover. The cost is $8 adults and children; $7 seniors; children under one, free. For tickets or more information, call 742-2002 or visit childrens-museum.org.
