The DIY Girls: How 12 teens invented a solar-powered tent for the homeless

That was the starting point for their invention: a solar-powered tent that folds up into a rollaway backpack. The girls and 10 others from their high school had never done any hands-on engineering work before, but with the help of YouTube, Google, and trial-and-error, they got it done. They hope that one day, their tent will improve the lives of people experiencing homelessness in their community.
