Construct five different models using ultralight parts and a rubber band powered engine.
This brilliant set features a fully detailed 16 page instruction booklet, showing you how to build five different models including an airplane, helicopter, fan car, airboat and a hydrofoil. Using a unique reversible propeller and ultralight parts, observe your builds in action as they fly through the air and speed along. Learn how propellers push vehicles forward, how rubber bands store energy and even how elasticity makes your boat zoom across the water! A fun and informative project build set that's very satisfying.
Nine year olds are clever little fellows and have lots of interests. Great presents for 9 year old boys are remote controlled cars or flying objects, science construction kits, anything that shoots, or outdoor gear. Magic is popular and anything involving pranks will appeal to that 9 year old sense of fun. Or get them a great book.
