We are studying the Middle East in history right now and one of the recommended projects was to make an edible oasis.The kids were very excited about this project. Probably largely in part to the fact that they got to eat the Oasis they made later.
Here's the finished creations. Some of them even have little boats in their water... how the boat got to the Oasis was never answered ;).
They all even waited to eat them until after they showed Daddy and Big brother!
