Construction begins in the playroom, with hands-on kid-designed mechanics. With tools and parts designed for young children, they get right to work. The nifty screwdriver with 3 bits is the just the power tool needed. Simply screw together pieces to complete the construction Crane. Once it's finished, kids spend long hours rumbling the crane through the living room, picking up toys in the bucket. Time for a tune up! Luckily there's a mechanic in the house. With screwdriver in hand, children take the entire crane apart, unscrewing piece after piece, until there's nothing left but a pile of thirty parts. Then, they put everything back together again!
