Thanks, those are both good ideas. (Batman: 2509235, Bob: 2, Everyone else: 0). I have to go to the Evil Store of Evil (Walmart) later today, so I’ll see if there’s any good options in the kitchen section. Might be a long shot though, it’s a pretty tight fit inside the arm. If not, I’ll try the second one, a paint stick is probably too big, but I have a good supply of coffee stirring sticks courtesy of Sheetz, so I’ll see how it goes.
