To make this very Simple Top you need a rectangle of paper 30-cm long and 10-cm wide, a cycle spoke, old ball pen refill and glue. Now curl the paper diagonally on the cycle spoke. Fold tightly to make a paper tube. Glue the triangular flap on the tube to prevent it from opening. Secure the tube by taping it at a few points. Then press the tube to flatten it completely. Then leaving about 1-cm from the tip, fold the flat paper tube tightly on an old ball pen refill. Glue the end of the paper on the disc to prevent it from opening up. Cut about 2-cm of the refill from the disc to complete the top. Hold the stem and see the top spin round-and-round. Because of the large disk and low center of gravity the top spins for a very long time.
