Rebecca Xun and Lucia Camacho built the Vape-o-Gotchi, a vape device that dies if you stop puffing.

There’s a big trend of parental locking yourself,” Camacho added. “I’m locked out of certain apps behind a password that Rebecca knows, so I don’t scroll Instagram too much. It would be cool if you could have that for nicotine.” But then, explained Xun, Camacho “found this Stupid Hackathon. And we were like, it’d be kind of funnier to be evil.” And with that, their “evil-mode” Vape-o-Gotchi, which instead rewards users for vaping, was born.
