Overview: Our annual "kids" episode features family-friendly projects that parents and kids can build together! First, landscaping contractor Roger Cook helps a 12-year-old budding master gardener build a raised bed for growing vegetables. Then, up in the loft, general contractor Tom Silva and plumbing and heating expert Richard Trethewey, with the help of several kids, build a miniature indoor golf course. Next, Kevin and a middle school teacher show some eager students how to build a model rocket launcher using commonly available household and hardware store items.
