When Jorge Odon, a car mechanic from Argentina, saw a YouTube video on removing a cork from a wine bottle, the gears in his brain started spinning. In a dream that night, he saw the method – which involved inflating a bag inside the bottle to force the cork out – applied to stubborn babies stuck in the womb. The next day, he built a prototype device in his kitchen to test his theory. It worked, and he then spent several years trying to get the attention of medical professionals so they could start clinical trials. If they succeed, it could be a godsend for women delivering in areas where a Caesarian section isn’t possible.
