I've been working on this thing for such a long time I almost can't believe I finally finished it. Like always I used a big candy ball from party city, a pokeball, a kool-aid container, some bionicle joints, and a bunch of foam board and craft foam. This time I held it together mostly with flex seal, I used hot glue before but I had a hard time getting the gun into the small spaces and the hot tip melted part of the ball once.
