Topic	will balloons be sold in outer space
Playsaver 07/20/20 12:57:29 PM #12:	I think the real question is "Could a balloon work in earth's atmosphere using only a vacuum in the balloon to cause it to rise and float." It would be working on the principle that causes stuff to float in water, which is that an object in water floats if its weight is displaced. So if you could make a balloon filled with nothing but a vacuum, it would have to displace its weight in air. --- This space for rent. 50,000$ per letter. <cite>Playsaver posted [p:942352132] in will ballo...
