A tale of a doubly twisted adventure
Motivated by a twisted lamp stand at a grocery store, I made a helical prism with standard sticky notes. Then, an encounter with a fallen leaf on the forest floor gave me the idea of making the structure doubly twisted, with two different colors. The study and calculation of the curved surface area and the volume is an engaging exercise in calculus. Also, a rotation of these structures gives off a pleasant illusion of motion, with a mesmerizing double motion for the doubly twisted structure.
