In real life, we often encounter a problem that we can not distinguish which bottle belongs to ourself when we drink the same band that botle are the same.
Now, the “Colorful Discriminating” bottle cap can solve these problem. Here are 9 kinds of colors on the botle cap, at the same times , the annulus matches the cap. In order to distinguish with each other, we can turn the annulus with a different angle, then we can get different color matchings ,then we can distinguish our botle easier.
