One Balloon Air Racer. The racer is 6.5 inch long, and 3.25 inch from the end of one wheel to the end of the other wheel. The set comes with one balloon race car and 2 latex balloons. There are 2 different car styles, so kids are going to love this! All you do is blow the balloon up, set the car down and the car will race across the floor with the power of the air coming out to the balloons. You can even make a game out of this. Set up a race area and the first one across the finish line wins. Please note that orders are filled randomly so there is no guarantee which color or style you will receive.
