1. The biggest problem we encountered was building the final model because we saw it had lots of flaws. At first we tried to make it stable but we couldn't. Then, we tried to make it pretty but is was hard so we stayed with practical and fun to play.

2. We got our biggest AH-AH ideas when we were talking about our prototype because it was when I came up with the idea of building the slingshot and its target because it was the funnest and simplest to use and it ended up affecting how the final phase would be. It was like the base of everything.

3. Nicolas Cruz resisted it the ideas the most because he thought that he idea was better and he did not like the one that ended up being the final one. He thought it would be hard to build and that it was going to be boring but it ended up being the best choice.

4. I had doubts about how the slingshot was going to be because at first we took a lot of time and effort and it did not work very well so I thought this would be our biggest issue. It ended up being it. I also asked myself if kids were going to like it and they did because let's face it, who doesn't like shooting.

5. Cruz played the devil's advocate because he questioned everything and did not like the ideas. It became frustrating but at the end he helped by finding a way in how to make the base stable. Also he helped in the design of the prototype of the slingshot.

6. I learned to work better in groups and to plan things. I also learned that always something can be made better or fixed in a way that is sometimes really hard but it can be done.
