Meet McKeyla McAlister, Project Mc2 leader! She's a writer, hipster, undercover spy. When she's not journaling, she's probably reading a Sir Arthur Conan Doyle novel, performing magic tricks, or trying to save the world.

Now you can perform a cool S.T.E.A.M. experiment at home just like Project Mc2 leader, McKeyla McAlister. Make your own cocoa bronzer using household items again and again. About the experiment: Humans discovered the recipe for chocolate almost 2,000 years ago, but cocoa powder (the basis of chocolate) wasn't invented until 1828. Cocoa powder comes from Cacao beans, but it can also be used to make your own bronzer! To create your own cocoa bronzer, start by mixing cocoa powder with nutmeg and coconut oil. Then, add the mixture into the bronzer case and use the puff to apply to your cheeks! Experiment with different measurements for endless combinations!
