The whole project went well to only problem was we would always run out of play doe. So we would have to stop make more play doe and then add it on, But once we got the right amount of play doe the whole volcano when together. The one major problem we had was that the play doe we would add would slowly slide down the structure. We decided to make a cinder cone volcano, but once we finished the top of the volcano did not look like a cinder cone so we redid the top and it looks pretty good(except for the play doe sliding down.
