Didn't want to start a new thread on Bestine soaking for FUD/FXD, but here's something completely different:
That's a little gadget called a "tea infuser". It's a spring-loaded screen clamshell, normally used to drown tea or herb leaves for one's favorite brew. After a few episodes chasing small parts around in jars of Bestine, I clearly needed something to corral the small bits. In this case, the small bits are 40 of Lemosteam's bridge shoes. Problem solved!
