<p>Now you can perform an experiment at home with Project Mc2leader, McKeyla McAlister. Make your own invisible ink pen just using household ingredients like baking soda and water.<br> Picking Up S.T.E.A.M.: <br> Your ink may seem invisible when you€re writing your secret message, but the pen is actually leaving a residue of sodium bicarbonate (aka baking soda). When you rub your paper with a berry or tea bag, the acid in those items creates a chemical reaction with the baking soda, a base. That reaction makes your message become visible.<br> <br> Doll Set Features: <br> - Premium, articulated McKeyla doll, dressed in her undercover spy outfit that reflects her individual style.
