Our Team Leader's favorite quote:
If at first you don't succeed, try more duct tape.

Why we think we should win:
Even though the middle school entry only needed 10 steps - we created 40!!! We organized ourselves in October and worked on our own during lunches and after school to build our machine. We had a great time, made some huge messes, and created something that was elaborate and crazy fun out of things we found around our homes. We even figured out how to build a magnetic accelerator using magnets, electrical tape, PVC pipe and metal marbles. We want next year's middle schoolers to get inspired and take on the Rube Goldberg contest challenge!

Suggestion for next year's challenge:
Write a word
