|Their teacher thinks these girls will soon become millionaires with this invention of the invisible helmet for cyclists. A nylon, hood-shaped airbag is built into a neck-collar which automatically inflates during a crash by a sensor system. The collar is on when the collar is zipped and buttoned, and off when the collar is open and unbuttoned. The collar also carries a LED light and a USB-port for charging the battery while also allowing information to be uploaded after a crash. It took them seven years of research in collaboration with hospitals  and studying reports of bicycle accidents. Since these are girls, they also took care of various covers for different looks, but they also raised $10 million from venture capitalists. .
