I found a great play dough recipe at Simply Moms and Friends.
The original recipeI found calls for 1 cup corn starch to 1/2 cup cheap hair conditioner with a few drops of food coloring.
I used a pomegranate and grapeseed VO5 conditioner. It smelled so good. Since my conditioner was pink it gave my dough a pink hint of color, so I skipped the food coloring to make the whole project a little simpler.
As we measured out our corn starch and conditioners I took the opportunity to discuss a whole and a half. When I first started mixed I got scared I had a gooey mess. So added some extra corn starch till I got a consistency we liked. I think if I had just kept mixing it at first I would have eventually gotten a nice fluffy consistency. I kept it a little on the dry crumbly side, DD was using the dough with some cars to drive through. I think our measurements were closer to 1 cup corn starch to 1/4 cup conditioner. DD had a ball playing with her cars in it. She loved making tire tracks through it and squeeze it in her hands. She got some great fine motor time in with it.
