Okay, I don't, for a minute think these three young girls came up with this all on their own. And it doesn't matter. What does is fewer than 3 in 10 graduates in science, technology, engineering, and mathematics are women. And barely 1 in 10 engineers are women. Why? Stereotyping? That's gotta stop. And this video is just the panacea.
Think of how much fun this must have been to build. Move over Rube Goldberg. Make way for Ruth Goldberg... and her friends.
