A challenge: Can you create a stable top from a single paper clip? Several interesting solutions to this problem were provided by Takao Sakai from Japan, the requirement of each being that the center of gravity be located on the vertical y-axis at the center of the top. In the simplest configuration, we see that there exists a single angle ? between the spokes for which this requirement is met (Figs. 1 and 2). While a rigorous calculation of this angle is a nice task for first-year university students, one simple approximation allows for a more high school-ready analysis. Even a qualitative study without any math makes for interesting and fun science.
