Dyes are added to the pellets to provide the many different colors available.
Why do diving masks cover the nose?
The reason is that the nose pocket of a diving mask is needed to compensate for increasing pressure as you dive deeper. The nose pocket allows you to blow air into the mask through your nose, equalizing that pressure.
