The chirality of chemicals is a well-known concept among undergraduates. The examples of chiral molecules in daily life are introduced to high school students as well. However, the chirality of single-walled carbon nanotubes (SWCNTs) remains unpopular in these groups. In this paper, a simple visualization of SWCNTs was first performed via paper origami. Then, a cost-effective separation experiment was introduced to the students to achieve the actual chiral SWCNTs. The proposed visualization and separation of chiral SWCNTs were evaluated in students' science projects. Introducing the chirality concept to students would enhance the students' understanding of nanomaterials and the chirality of SWCNTs.
