Paper cylinders are very simple to make and require very few supplies. The project can be used to demonstrate the shape of a cylinder and to explain a cylinder's geometric properties for a maths lesson, or it can serve as a fun activity. Paper cylinders can be used to create play binoculars, or towers for a model of a castle for a history project. Learning to make a basic paper cylinder will help you create objects for other projects.
Cut a sheet of paper with scissors, so that it is as long as you want your cylinder to be.
Pull one edge of your paper over and roll it into the opposite edge so that it overlaps the opposite edge by about 2.5 cm (1 inch). Hold it in place with your finger.
Straighten the paper so the sides are even and place a piece of tape along the edge to hold it in place.
Place the cylinder on top of another sheet of paper and trace the circular opening twice with a pencil, if you want to close the top and bottom of your cylinder.
Cut the circles out with your scissors and tape one over each end of the paper to enclose the cylinder.
