We are a free build group.Our Team Leader's favorite quote:
"Failure is an option, but then we just keep on going." Team That Was Easy 2019
Our machine is about things that you might think will be easy in the beginning but actually turn out to be hard, just like this machine. We started with an Easy Button and joking how building the machine was going to be easy. We actually found it be challenging. Some of our parts didn't work, but we never gave up. Even though we found it hard, we still continued on and wanted to finish. Keeping it funny by joking about it being easy helped us keep a good attitude. The machine has many parts, including containers, hot wheel cars, train tracks, fishing line, wood, metal brackets, pulleys, levers, a wind-up toy reinvented, and, of course, a piggy bank. We hope you enjoy.
