Become an aeronautical engineer with the B. Build-a-Ma-Jigs Toy Aeroplane. Play the part of the mechanic and take your airplane apart and put it back together again to learn how it works. Its propeller and wheels spin and the rudder moves, just like the real thing. This 22-piece set includes a play power drill and three interchangeable bits. The pieces of this kit are interchangeable with other BUILD-A-MA-JIGS sets. Give the gift of engineering with toys and gadgets that foster curiosity and encourage scientific learning. 2-AA batteries are required for operation (not included). Recommended for ages 3 and up.
