“FROM TIME TO TIME, there was talk among the astronauts that it might be nice to have a drink with dinner. Beer is a no-fly, because without gravity, carbonation bubbles don’t rise to the surface. “You just get a foamy froth,” says Bourland. He says Coke spent $450,000 developing a zero-gravity dispenser, only to be undone by biology. Since bubbles also don’t rise to the top of a stomach, the astronauts had trouble burping. “Often a burp is accompanied by a liquid spray,” Bourland adds.”
