Product Description

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.
Picking Up S.T.E.A.M.:
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.

Doll Set Features:
- Premium, articulated McKeyla doll, dressed in her undercover spy outfit that reflects her individual style. Her gloved hands make sure she leaves no fingerprints behind. So many fun details!
- Includes a fun science activity: invisible ink pen to experiment again and again
- Household ingredients not included
- Accessories for the doll include: McKeyla's Ultimate Lab Kit, beanie hat, spy disguise glasses, and beaker-shaped comb
- Ages: 6+ years
