New Girl-Power Dolls Come With Their Own Experiment Kits

"Project MC²" is geared for tween girls.

The dolls are also designed specifically to represent “real girls.” Each doll is engineered to stand at a different height and is made with “premium hair, glass eyes and rooted eye lashes to help deliver a natural and realistic aesthetic,” the company said in a statement.

MGA's own CEO, Isaac Larian, is a civil engineer by trade who says he remembers there being only one female in his classes as a young engineering student.

"She was frankly the smartest one in our whole class," Larian told ABC News. "The taboo that females cannot be engineers, mathematicians or businesswoman, has to be dealt with. That was my inspiration."

The creation and production of the dolls took nearly three years and included the hiring of a team of scientists to make the dolls as authentic and accessible as possible.

"Once we had the idea, we wanted to make sure it was real and not phony," Larian said. "We wanted the dolls to have experiments where girls could use household materials to create the scientific experiments and, hopefully, inspire them to take classes later."

The series geared to tweens, or 10- to 12-year-olds, is a smart fit for McKellar, who took a break from acting to earn her mathematics degree from the University of California Los Angeles (UCLA) and then went on to write books like “Math Doesn’t Suck” and “Kiss My Math” targeted at girls.

McKellar took to Twitter today to promote the new series.
