This is a magic bookshelf that can help to balance your knowledge. Put on each end of the shelf different books, for example, books on economy on the left and cartons on the right.
The end on which more books are assembling will be bending downward with the other one warping upward, reminding the owner to stop buying cartons. The two removable wooden frames, in which vases and picture frames are placed, play the role of weights. Put more things in the frame or adjust directions if you want to have more books on one end.
