Lowe's offers these great how to clinics for the kiddos a couple times a month. They are a great way for children to learn new skills. When you bring your child to Lowe's on Saturday, November 13 at 10 AM and they can build this cool working periscope! Wouldn't it be a cool gift to give to have your child give to a friend for a birthday or Christmas gift? Be sure to register in advance.
