Summer adores Project Mc2, she watches it on Netflix and has many of the Project Mc2 toys, including quite a few dolls. 

Project Mc2 is all about encouraging STEM, particularly for girls. The Netflix series is a group of super cool friends who go to school together and are in a secret club. Adrienne Attoms, Bryden Bandweth, Camryn Coyle, Devon D'Marco and Ember Evergreen and McKeyla McAlister, all love to celebrate and share their love of science.

To complement the Netflix series there are gadgets and toys available to buy for your STEM-loving, Project Mc2 Loving, child! The toys introduce an array of fun and exciting experiments, getting your little one involved and hopefully in love with STEM.

For this review, we were sent the Project Mc2 A.D.I.S.N Secret Journal - which Summer has wanted a secret diary for a long time (to hide her secret notes from her brothers). 

The Project Mc2 Secret Journal is an advanced digital intelligent spy notebook, which includes a NeRDY bracelet (which is covered in some cool scientific symbols on it) to scan the front of the secret journal to open it. 

Once open, is a compartment to place your mobile phone in. Once you download the Project Mc2 A.D.I.S.N journal app, the app gives you missions from NOV8 to complete, allowing you to interact with your super secret journal. How fun!

In addition, there is a secret pen, which allows you to write secret messages on the inside of the journal, and to reveal the message you use the UV light. You can wipe clean the message and new ones can be written! Finally, there is a mission book and stickers.

Summer loves her Project Mc2 5 A.D.I.S.N. Secret Journal - she takes it very seriously, writing lots of secret messages in it. She also has fun with it, playing with it hours on end.
