Playdough...gone wrong!

So I decided to attempt making play-dough from scratch.  I thought it would be fun to let the boys help me color the dough.  I didn't have any cream of tarter, so I found a recipe online that didn't require cream of tarter.  It was a bad recipe!!  The dough didn't set up enough and it was a mess.  Plus our 3yr foster son had dry hands and I didn't realize it.  Within a minute of playing he started complaining that his hands hurt from the salt!!  Needless to say, play-dough time was quickly over.  What a fun little mess!
