This is the model kit reinvented—build 12 different models that run on two forms of alternative energy, solar and hydraulic power.
OWI has done it again with this excellent 230-piece model kit. Build your own robot in any number of 12 pre-planned models that can be easily assembled using the instructions. The included gear box is a double threat that requires no batteries, and uses solar and hydraulic energy in tandem to create a truly green energy kit. Young engineers will have a blast actively learning about two forms of alternative energy that work in tandem with their imagination. Build a moving scorpion, forklift, t-rex, and more!
This is Bart Simpson's age. Fun presents for 10 year old boys are things that provoke the imagination or provide a challenge. Any toy involving running around outside is good. A kite makes a great present for a ten year old and they probably won't get it eaten by a tree. Ten year olds like more sophisticated books, doing interesting experiments and building things.
