The smartest girl spies of all time are back! These four girls and their science and tech skills will have you smiling every single time with their adventures.

Do you love science? Do you have a passion for learning new things? If so, then Project Mc2 is the group for you! They're super smart and seriously cool girls who use their love of science and their spy skills as they go on missions for secret organization, NOV8 (that's 'innovate'!). They're real girls with real skills ready to take on anything. Just like them, you can conduct your very own experiments at home! Now you can perform a cool S.T.E.A.M. experiment at home--and with just a few simple ingredients from around the house, too!
