Google got stumped on this one! Or, I gave up after a few erronous links... I'm gonna guess you tie one large horse to the basket. If the balloon stays down, you have less than 1 horsepower, if it goes up, then you have more than 1 horsepower, if it stays stationary, you have exactly 1 horsepower...NC19143 said:How is the horse power of a balloon determined?
