Balloon Car Builder 1.0
You've built a car with a balloon "engine" and now its time to test it out.
Hey, it goes pretty far, but will it go farther if you change some things? Try bigger wheels, or a smaller box...how about a smaller opening for the balloon to fit into? Balloon Car Builder will have kids using their thinking skills and creativity to try to get the car to go the furthest it can! Good luck!
