Well done, Columbia! You guys did a great job.
I appreciate the blueprint of your plan and the explanation in your video.
Great work future engineers!
“Chachow!”
Great teamwork. Looks like you had fun learning about energy transfers.
I liked seeing your sketch and the excitement everyone had when the ETM finished.
Great project! Teams of 5 always allow for great teamwork. The transitions in the video were also great! The only thing to work on here would be increasing the length of the machine. Otherwise, great work!
