These are transforming tea bags. One starts out as a stressful symbol that changes to a calmer version once you put it in hot water. Smart! They were created by ad agency M&C Saatchi for tea company BOH, who was hoping to convey their chamomile tea has a calming effect. Well, guess what? It worked! You drove the point right home and didn’t crash through my living room doing it! Which would’ve been bad advertising, so good job on that.
