I've created a list of fast, easy and fun ideas and all you need to do is add water to them and start playing! I'm going to *highly suggest* you collect the items right now and put them in a bin for later. Then, when you are in need of something that you can just grab to entertain your kids in those difficult moments... you'll have this bin full of fun, all ready. And yes, all you'll need to add is water. You really can't get any easier than that.
