On the first Saturday of each month at each and every HomeDepot store, free "How-To Clinics" are offered for kids ages 5-12, from 9:00 a.m. till noon. Kids must be accompanied by an adult.
What happens here? Cool stuff is made. From pre-fabricated kits, kids make toolboxes, stepstools, fire trucks, mail organizers, window birdhouses, bughouses, and frames - among other things.
Each child also receives an achievement pin and his own orange HomeDepot apron. There's no limit, either: you and your child can go every month, if you'd like.
