How Do You Build A Balloon Race Car For A High School Student?
High school students build balloon race cars for illustrating science principles. A balloon race car can be made out of almost anything with a balloon strapped to it, but for simplicity and to save time, but to still give the car a home-built look, Legos or other blocks may be used. Consider that the easiest way to make a balloon race car is to strap a balloon (already inflated) to a toy car of your choice, then let it go so that it is propelled forwards by the thrust of the air escaping out of the same hole that the balloon was inflated through. The ideal car would be lightweight and have little friction on the wheels. The wheels would have to be clear of the balloon to avoid interference from the balloon. Use plastic construction blocks like Loc Blocs, Legos, K’nex, Tinker Toys or other blocks/modeling systems to give the car a “built from scratch” appearance. Start with a long “backbone” of blocks that resembles a headless stick figure with the “arms and legs” going out at 90-degree
