Through the heat contraction tube, the collision sphere experimental vessel which joints sphere and the thread, hangs sphere.

摘要

Topic Joint of sphere and the thread being easy, the collision sphere experimental vessel where the thread does not deviate from sphere is offered.SolutionsIt passes through the thread to top of the heat contraction tube which at the length which is briefer than diameter of sphere is sliced. After inserting sphere in this heat contraction tube, when it adds heat, the heat contraction tube contracts, sphere and the heat contraction tube fit. Because of this, through the heat contraction tube, sphere and the thread are jointed, sphere is hung. Choice figure Drawing 1
