One part of our team uniform is our rally towel. These are twirled during team introductions. Also, when down on the floor during slow times, the drive team will twirl their towels at the team in the stands until everyone notices and everyone in the stands is twirling back.
We give our alliance partner drive team members towels of their own. These sometimes get used in creative ways.
After Galileo alliance selections, 973, the Greybots, loaned us their spare retractable blocker arm, which we mounted on our bot. They let us keep it after Championships. After we got bumped on Einstein, we removed the net from our pickup arm and cut it in four pieces. We gave one piece to each of our alliance partners, and kept one as a memento.
