LEGO Crazy Action Contraptions
What a cool collection of whacky, brilliant, off-kilter gizmos! But get a load of the 16 different high-impact, high-performance vehicles and contraptions kids can create with them. A great, 50-pg book from Klutz makes following instructions as much fun as building. Includes every LEGO brick, gear, wheel and axle kids need to make it happen. From Klutz for ages 7-12 yrs.
