This is one of my favorite ice-breaker activities, and it can also be used as a debriefing/reflection tool. It is just a collection of little charms and miniature objects, but in my experience learners love putting their hands on them. It is an instant change in atmosphere from afraid to talk to eager to explain their choices: a real conversation starter that encourages deep thinking through metaphorical connections. For this reason I think it is perfect for language learners who have so much more to say than their level of fluency and speech anxiety will sometimes let them.
