Spooky Surprise Playdough Mix

This is what I made the kids for Halloween.  It is the dry mix to playdough.  I mix in some powdered orange kool-aid, so when they add the liquid ingredients it instantly changes color (that's the surprise!).  I give them each a Halloween cookie cutter too!  Once they make the playdough, then they have an airtight container to keep it in.  I couldn't find the orange ones they always have at Halloween, so I had to settle for red.  It was driving me crazy, but oh well!
