I have all thirty of the floating message capsules carved down to their own individual, unique contours. The high grade blue styrofoam is exponentially more durable and less messy than the typical styrofoam. However, it is still IMPOSSIBLE not to get it everywhere. I sweep and sweep and sweep; I spray off my clothes with air; I sweep again. I STILL find blue foam dust in my car, clothes, and apartment at the end of the day.
