I found this idea in the Family Fun magazine. They called it Preschool Potions. It was a pretty simple idea...just cornstarch and water....that I thought could be fun sensory activity for jake and anna. I'm trying to find activities that they could both do and this fit the bill. Meaning it was non toxic because everything goes into her mouth. I'm not going to lie. I was enthralled by the stuff. Its really a lot cooler in person than it is in pictures. I even saved it to show Trev when he got home. The nice part is clean up is a breeze. It just turns into cornstarch when it dries.
