Levelling Card

The density of liquid is greater than air,so air bobble of an inclosed container will float on the liquit.
When the bobble is in the middle place of the container,the container is aclinic.So follow the bobble we can put the object in an aclinic place.
This concept is about a small container which can paste on objects’ surface,and adjusting the object by the position of air bobble conveniently.
With this,we will have no trouble in hang photo frames,pictures or other things on the wall.
