I made a rube goldberg machine. It is made up of small simple machines. These include levers, pulleys, ramps, and more. I used a large assortment of materials to make it. Some of these include Legos, tinker toys, cardboard, tape, string, dominos, and a train. 

I got the idea from my physics teacher. I worked with 2 friends from school. Our plans changed many times as we worked. At the beginning we only had around 5-6 steps. When it was finished we had thought of many more.

It was built at my house. We worked on it at school by coming up with ideas for steps during lunch.  

The biggest challenges were getting some of the steps to work. I am proudest of the ATAT. If I had to do it again, I would eliminate some of the harder steps such as the zip line, and add in others.
