The Rehoboth Beach Museum is inviting area children to answer the question: How do ships talk to one another without making a sound? The answer is by using nautical flags that represent each letter of the alphabet. Ships can “talk” to each other by waving flags when in sight of each other. Each letter of the alphabet has its own flag with a design on it. The Rehoboth Beach Museum is hosting a children’s program on Friday, April 21 from 11 a.m. to 12 p.m. for children ages 8 to 11 featuring a story book and a craft activity allowing each child to create a banner with nautical flags spelling out his or her name. A $5 donation is requested and reservations are strongly suggested. Please call (302) 227-7310 to reserve a spot. The museum is located at 511 Rehoboth Avenue. Parking is free and the museum is handicap accessible.
