Homemade playdough...

A great way to clam little boys down is to throw some flour, salt, kool-aid package, oil, and water in a bowl.  Mix it all together, put some flour on the counter top and give each one a ball of dough.  Tell them to kneaded it and have fun.  After they are done explain to them that they just made homemade play dough.  The looks on their face is priceless to me.
