Gluten free playdough...fail!!

So for the sake of being the best Sunday school teacher ever I figured I would make some gluten free playdough. The idea being that then all the kids in the class, even the one with the gluten allergy could play. How hard could gluten free playdough be? I mean all it is is playdough made with rice flour right....apparently not. I failed at this and have a photo to prove it. I may just be telling gluten free kid that playdough is off limits :(
