Rubber band powered race cars are so much fun to build because they are fun to race once they are built. The zoom across the room at high speed and racing with friends becomes a big competition. The child not only has fun doing this, but they learn valuable lessons on building things themselves and getting that understanding about cars as well. The most important lessen they will learn is that everything in the world is built with a different systems that work together to make the structure work as a whole. A car is a complex instrument we have learned how to build and created because of one simple concept: getting from point A to B quicker. If you walk versus drive somewhere, there is a very high chance that you will get to that point quicker because of the speed the car will give you. It is an interesting concept that every child will eventually learn and the Playsteam Green Powered Grand Prix rubber band race car will help them learn it well!
